which of the following correctly describes the impact of an abiotic factor on the population dynamics of an ecosystem?
herbivores will not be able to deplete the plants and other resources in an ecosystem due to predation.
organisms that compete for the same resources will keep each other from over populating.
seasonal variations in temperature and precipitation can cause some of the individuals in a population to die.
a parasite that invades a host can reproduce and cause a decline in the host species population.

Explanation:

Abiotic factors are non-living components (e.g., temperature, precipitation). Seasonal variations in these affect population dynamics by causing mortality. Other options involve biotic factors (predation, competition, parasitism).

Answer:

C. Seasonal variations in temperature and precipitation can cause some of the individuals in a population to die.
