Hope this helps!

To find the answer to this question, let's review the options provided: A, B, C, and D.

Since the question is asking for the maximum number of something that an ecosystem can support, we can eliminate options B and C, as they represent variables that are unrelated to the concept of carrying capacity.

Now we are left with options A and D. To determine which one is correct, we need to recall what carrying capacity refers to in the context of an ecosystem.

Carrying capacity is the maximum number of organisms or population size that an ecosystem can sustain over a long period of time without causing significant harm to the environment or depleting essential resources.

Given this definition, we can conclude that the answer is option A – organisms. Therefore, the maximum number of organisms that an ecosystem can support is the carrying capacity.
