question 8 of 10
which statement explains how a stable ecosystem can exist even while the populations in it vary over time?
a. if individuals in a population cannot find shelter, they will use new abiotic factors for shelter so the population can continue to grow.
b. if a prey population grows, it will decrease the size of the predator population because the predators will have less competition for food.
c. less rain one year will cause populations to decrease due to a lack of food, and populations will stay at this reduced size even when rain returns.
d. if a disease spreads through a population that has a lot of genetic variation, resistant individuals will survive and the population will recover.

Explanation:

Genetic variation allows for population resilience. Resistant individuals can survive diseases, enabling population recovery and ecosystem stability.

Answer:

D. If a disease spreads through a population that has a lot of genetic variation, resistant individuals will survive and the population will recover.
