Question

what does carrying capacity refer to? *
○ maximum number of individuals an ecosystem can support
○ how much food each organism can carry
○ the weight of a population
○ the number of births in a year

Explanation:

Carrying capacity in ecology (a subfield of Natural Science, specifically Biology or Environmental Sciences) is defined as the maximum number of individuals of a species that an ecosystem can sustainably support, considering available resources like food, water, and space. The other options are incorrect: "How much food each organism can carry" is unrelated to population ecology; "The weight of a population" is not a standard ecological term; "The number of births in a year" refers to birth rate, not carrying capacity.

Answer:

A. Maximum number of individuals an ecosystem can support
