Logistic growth carrying capacity concept – UGC NET Question

Logistic growth describes a population pattern where growth is initially rapid but slows as resources become limiting. The curve eventually levels off at the carrying capacity,forming an S shaped pattern. This model reflects the influence of environmental resistance on population expansion. Thus the description in the question corresponds to logistic growth.

Option A:
Linear growth implies a constant increase by the same absolute amount over equal time intervals. It does not show slowing down as the population approaches a limit. Therefore it does not match the S shaped pattern described in the stem.

Option B:
Logistic growth incorporates both the initial exponential phase and the later plateau at carrying capacity. Environmental constraints such as food shortages or space limitation cause the slowdown. This behaviour makes logistic the correct term for the question.

Option C:
Exponential growth describes a J shaped curve where the population increases by a constant proportion without resource limits. It does not stabilise at a carrying capacity within the model. Hence it is inconsistent with the description given.

Option D:
Cyclical growth refers to populations that fluctuate regularly over time due to seasonal factors or predator prey dynamics. While it involves variation,it is not characterised by a single plateau at carrying capacity. Therefore it is not the best answer here.
