Populations that exhibit logistic growth still exhibit exponential growth. This statement is:
adoni [48]

Answer: Option B (True)

Explanation: The statement can only occur in different populations of the same organism. The two growth strategies happens in different modes.

Firstly, logistic growth occurs when the resources available in the habitat (i.e organism’s niche) are limited to satisfy the whole population and this allows the organisms of the same species to grow rapidly until it reaches the point the resources can circulate, the carrying capacity.

While exponential growth occurs when there's abundance of resources for the population and allows growth of population beyond the carrying capacity, which results to overshoot of population in later stage of growth.

Secondly, in logistic growth population rarely crash but in exponential growth, population crashes due to mortality (often by predation, disease outbreak and etc) when there's overshoot of population beyond the carrying capacity.

Note: Population refers to the total number of organisms of the same species inhabiting a geographical area at a particular time.
