Bats may be greater in number in a habitat with abundant flying insects and roosting sites, but fewer in number where there is abundant food but fewer suitable shelters. which relates to this observation?

a) exponential growth
b) logistic growth
c) limiting factor

Option C, Limiting Factor

Explanation:

In case of “limiting factor growth model” there is one or more factor which limits the growth of population of an species irrespective of other factors favoring its growth. Like in this case though there is abundant food, if the shelter is not suitable the bat population will not grow. Thus, if only the limiting factor “suitable shelter” is provided along with abundant food, the population of bat will shoot up. Hence, option C is correct.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
