UGC NET Questions (Paper – 1)

Statements A, C and D correctly describe multiple ecosystem services of urban green spaces. Vegetation can reduce heat island effects, enhance air quality, provide habitats and extend greenery through roofs and walls. Statement B is incorrect because urban green spaces are recognised for supporting mental health, recreation and social interaction. Hence the combination that includes A, C and D while excluding B is the correct answer.

Option A:
Option A is incorrect because it includes only A and C and leaves out statement D. While A and C are true, D is also a correct statement about green roofs and walls contributing to urban greening and climate adaptation. Omitting a true statement makes this option incomplete.

Option B:
Option B is incorrect because it treats B as correct along with A and C. Statement B wrongly denies the psychological and recreational benefits of green spaces, which are well documented in urban planning and public health literature. Including this false statement invalidates the option.

Option C:
Option C is correct because it groups exactly the three accurate statements A, C and D and excludes the one false statement B. It reflects a rounded understanding of how urban green infrastructure contributes to cooling, air quality and biodiversity as well as innovative building-level greening.

Option D:
Option D is incorrect because it accepts B, C and D. The presence of B, which incorrectly claims no role of green spaces in mental health and recreation, makes the overall combination wrong even though C and D are true.

Ecosystem services is the standard term used to describe the diverse benefits humans derive from nature,including provisioning,regulating,cultural and supporting services. The stem lists specific examples like climate regulation and water purification,which fall into these categories. Therefore services is the correct word to complete the phrase ecosystem services. Option D is correct.

Option A:
Stocks refer to quantities of natural capital/resources; they do not directly mean the benefits and functions listed in the stem.

Option B:
Goods usually mean tangible products (timber,fish) and do not fully cover regulating functions like climate regulation and pollination.

Option C:
Flows describe movements of energy/materials; “ecosystem flows” is not the standard umbrella term for human benefits.

Option D:
Services is the accepted term for ecosystem-provided benefits like regulation, purification and pollination,matching the stem.

In the Millennium Ecosystem Assessment framework, pollination is classified as a regulating service because it regulates plant reproduction and crop yields without itself being a harvested product.

Option A:
Incorrect; timber is a tangible product taken from ecosystems and is therefore a provisioning service.

Option B:
Correct; pollination is a regulating service that supports agricultural production by mediating an ecological process.

Option C:
Incorrect; spiritual and recreational benefits are cultural services, reflecting non-material values people derive from ecosystems.

Option D:
Incorrect; genetic resources provide raw biological material for breeding and biotechnology and are classed as provisioning services.

Statements A, B, C, D and F are correct and collectively describe ecological, functional, cultural, climate and economic dimensions of biodiversity. Biodiversity supports key services, loss harms livelihoods, cultural meanings are important, conservation aids mitigation and adaptation, and payment schemes reward service provision. Statement E is wrong because biodiversity clearly remains essential for food, health, materials and cultural identity even in modern societies. Therefore, the combination that includes all true statements and excludes E is correct.

Option A:
Option A is incorrect as it omits F, which correctly notes the role of payment for ecosystem services in incentivising conservation. Without F, the answer misses an important policy mechanism linked to ecosystem services.

Option B:
Option B is incorrect because it leaves out C while including F. Cultural services are a standard category in ecosystem service frameworks, so excluding C gives an incomplete view of biodiversity’s contributions.

Option C:
Option C is incorrect as it includes E, a statement that denies the relevance of biodiversity to modern human well-being. Since E is clearly false, this combination mixes correct and incorrect statements.

Option D:
Option D is correct because it aggregates all the accurate statements—ecological, livelihood, cultural, climate and economic—and excludes only the claim that biodiversity has no relevance. It thus reflects the integrated role of biodiversity in people, development and environment.

Statements A, B, C and D are correct as they list key drivers of biodiversity loss and main strands of conservation responses. Habitat change, overuse and invasive species are major pressures, and protected areas, restoration and sustainable use are core strategies. E is wrong because biodiversity loss undermines ecosystem services and human well-being, and F is wrong since climate change is a significant driver shifting species distributions and extinction risks. Thus, the correct combination is A, B, C and D only.

Option A:
Option A is incorrect because it omits D, thereby ignoring the variety of conservation strategies employed to tackle biodiversity loss. Without D, the answer mentions only pressures and not the policy and management responses.

Option B:
Option B is incorrect since it includes E, which falsely claims that biodiversity loss has no implications for ecosystem services. Accepting E contradicts the central theme that biodiversity underpins services such as pollination, water regulation and cultural values.

Option C:
Option C is incorrect as it includes F, which denies the link between climate change and biodiversity loss, while also excluding A. Dropping habitat destruction, one of the most important drivers, makes the combination incomplete and conceptually weak.

Option D:
Option D is correct as it contains all four accurate statements on drivers and responses while excluding E and F, which downplay consequences and disconnect climate change from biodiversity loss. It matches the integrated understanding presented in the unit.

Statements A, B and D are correct because they describe the standard classification of ecosystem services and give examples of regulating and cultural services. Provisioning, regulating, cultural and supporting services are recognised in major assessments, and pollination and climate regulation are key regulating services. Recreation and spiritual values are central cultural services. Statement C is incorrect since the concept explicitly links ecosystem functioning to human well-being. Thus, A, B and D together form the correct combination.

Option A:
Option A is incomplete as it includes only A and B and omits D. Without cultural services, the answer fails to capture the full range of acknowledged ecosystem service categories.

Option B:
Option B is correct because it groups all accurate statements and excludes C, which wrongly claims that human well-being is ignored. This reflects the accepted framework used in environmental economics and ecology.

Option C:
Option C is incorrect because it accepts C along with B and D. Including C undermines the purpose of the ecosystem services framework, which is precisely to highlight human dependence on ecosystems.

Option D:
Option D is incorrect as it combines A with C and D and treats C as true. Although A and D are correct, the presence of C makes the overall combination conceptually wrong.

Statements A, B, C, D and F are correct because they show how biodiversity underpins services, provides livelihoods, is conserved through protected areas, is threatened by invasives and must be used sustainably. Statement E is wrong since biodiversity loss affects health and cultural values. Thus, the correct combination excludes E.

Option A:
Option A is correct as it includes all true statements and excludes E.

Option B:
Option B is incorrect because it includes E (false).

Option C:
Option C is incorrect because it omits A and includes E (false).

Option D:
Option D is incorrect because it includes E and omits C.

A green belt is a zone of protected open land, often with forests,parks or agriculture,around an urban area. Its purpose is to check uncontrolled urban expansion,conserve natural landscapes and provide recreational spaces. The stem mentions a ring of open land around a city with ecological benefits,which fits the concept of a green belt exactly. Hence green belt is the correct term.

Option A:
Green belts are used as planning tools to contain cities within defined boundaries and to preserve peri urban ecosystems. They can also help moderate urban climate and improve air quality. These functions align closely with the description in the question.

Option B:
An industrial corridor is a designated area for concentrated industrial development,usually with high infrastructure and transport connectivity. It tends to attract more construction and pollution rather than limit sprawl,so it is the opposite of what the stem describes.

Option C:
A transport hub is a node where multiple transport modes or routes converge,such as a major railway station or bus terminal. It is typically built up and does not refer to protective open land surrounding a city.

Option D:
A free trade zone is an area where goods can be imported,stored and re exported with minimal customs restrictions. It is an economic instrument and not an environmental or planning measure to preserve open land,so it does not match the stem.

The Ramsar Convention,adopted in the Iranian city of Ramsar in 1971,is dedicated specifically to the conservation and wise use of wetlands. It establishes a list of wetlands of international importance and promotes integrated management. The stem clearly refers to an agreement on wetlands,so the correct answer is the Ramsar Convention.

Option A:
The Basel Convention deals with the control of transboundary movements of hazardous wastes and their disposal. It is an important environmental treaty but does not focus on wetlands,so it does not match the description in the question.

Option B:
The Ramsar Convention encourages countries to designate suitable wetlands and to maintain their ecological character through national planning. This emphasis on wise use aligns perfectly with the stem.

Option C:
The Stockholm Convention targets persistent organic pollutants,aiming to eliminate or restrict their production and use. It is not concerned primarily with wetlands conservation.

Option D:
The Montreal Protocol is an agreement to phase out ozone depleting substances to protect the ozone layer. Although also environmental,it has a different focus from wetlands management.

Natural wetlands slow the flow of water, trap sediments and nutrients and store floodwaters, thereby purifying water and moderating flood peaks.

Option A:
Incorrect; treating wetlands as wastelands ignores their important ecological and hydrological functions.

Option B:
Incorrect; intact wetlands generally reduce downstream flooding by temporarily storing and slowly releasing water rather than rapidly conveying it.

Option C:
Correct; it recognises wetlands as natural filters and buffers that improve water quality and moderate floods.

Option D:
Incorrect; wetlands are also rich habitats that support high biodiversity, so their role goes far beyond recreation.

Urban green planning involves designing and managing vegetation,parks and green corridors to enhance environmental quality and livability in cities. Street tree plantations directly contribute to this goal by improving air quality,providing shade and mitigating noise. The stem describes exactly such activities,so “green” planning is the correct term. Therefore Option D is appropriate.

Option A:
Industrial planning focuses on industrial location and development,not on integrating vegetation for ecosystem services in cities.

Option B:
Transport planning addresses mobility networks; tree planting can support it but the activity described is primarily about greening and ecosystem benefits.

Option C:
Energy planning concerns supply and demand of energy systems,not roadside tree programmes for pollution and shade benefits.

Option D:
Green planning explicitly integrates natural elements to improve air quality,shade and noise reduction,matching the example in the stem.
