Question

which of the following is a density - dependent factor in an aquatic environment? choose 2 answers: a water pollution from deep - sea mining b changes in oxygen levels from a tropical storm c parasitism by an endoparasite d competition for limited habitat

Explanation:

Density - dependent factors are influenced by population density. Parasitism (C) increases as host population density rises as it's easier for parasites to find hosts. Competition for limited habitat (D) also intensifies with higher population density. Pollution from deep - sea mining (A) and oxygen level changes from a tropical storm (B) are density - independent factors as they are not directly related to population density.

Answer:

C. parasitism by an endoparasite
D. competition for limited habitat
