Question

1. a population continues at a stable size for many years. suddenly, in a single season, the population size drops by half. is the cause more likely to be density - dependent, density - independent, or both? explain your answer.

Explanation:

Density - dependent factors are related to population density. A sudden halving of a stable - population suggests factors like competition for resources, predation, or disease, which are density - dependent. Density - independent factors usually affect populations regardless of density, like natural disasters or extreme weather. Since the population was stable and then suddenly dropped by half, it's more likely due to density - dependent factors as they can have a significant impact on a population at a certain density level.

Answer:

The cause is more likely to be density - dependent.
