Answer:
Explanation:
First, let’s define population. A population is all of the organisms of the same species that live in a certain area.
Now, let’s analyze the answer choices.
A: All of the different kinds of fish that live in a lake.
This is not a population, because a population is one species, and this is all the different species of fish.
B. All of the living and nonliving things that interact in and around a lake.
This is also not a population. A population is just one species, while this includes all the biotic and abiotic factors.
C. All of the trout that live in a lake.
This is a population. Trout are one species, and it is all the trout in one specific area.
D. . All of the fish, bacteria, and mammals that live in a lake
This is not a population. Fish, bacteria and mammals are too many species for a population.
Therefore, the correct answer is C. all of the trout that live in a lake.
