Question

In density-independent populations, birth rate and death rate do not change with population density. In contrast for density dependent populations: A. Birth rates decrease and death rates decrease B. Birth rates increase and death rates increase C. birth rates decrease and death rates increase D. birth rates increase and death rates decrease

Answer 1

Answer:

C. birth rates decrease and death rates increase.

Explanation:

In density dependent populations, birth rates of organisms decreases and death rates increases because of various factors that affected the rate of reproduction and survival. Higher mortality and lower growth rate occurs when there is disease, competition, and predation in that organism. These three factors decreases the birth rate and increases death rates in the population of an organisms.
