Answer:
B) Habitat
Explanation:
-A habitat is an organism's physical environment. A niche is the role an organism plays in the environment in which it lives. An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces. A species' niche includes all of its interactions with the biotic and abiotic factors of its environment.
-Habitat determines niche. An organism's adaptions to its habitat determine its niche.
-Adaptation is an inherited trait that increases an organism survival in its environment. A change in habitat can result in a change in niche. Competitive exclusion principle states that two species cannot occupy the same niche in the same habitat.
The picture is not that clear but A is probably the answer.
