Population x and y live in the same area. the size of population x increases over time. as a direct result, the size of population y decreases.
a. individuals of population x are predators.
b. individuals of population x are prey.
c. individuals of population y caught and spread a disease.
d. individuals of population y lost their shelters after a flood.
which is most likely the limiting factor of population y?

A. Individuals of population X are predators.

Explanation:

The size of population X increases and simultaneously the size of population Y decreases then the most like possibility is that individuals of population X are predators of individuals of population X. The population of X is increasing because individuals of this population are hunting individuals of population Y because of which their population is growing as they do not have intraspecific competition for food. This is also the reason why population of Y is decreasing because more predators means more hunting of Y individuals. Option C is wrong because if Y individuals are dying due to disease then the population of X can't increase because it means that Y decreased because of natural cause not because they were fed upon by X. Likewise option D is also wrong because population Y lost their shelter because of that they died not because of hunting by individuals of population X.

c. establishing proper sleep hygiene
