Question

which of these factors would cause an increase in a prey population? poor climate a lack of precipitation an increase in prey diseases a decrease in predators

Explanation:

In an ecosystem, prey populations (like moose here) are influenced by factors such as predators, food availability, diseases, and climate. A decrease in predators (e.g., wolves for moose) means less predation pressure, allowing more prey to survive and reproduce, thus increasing the prey population. Poor climate (option A) and lack of precipitation (option B) usually harm prey by reducing resources or habitat. An increase in prey diseases (option C) would kill more prey, decreasing the population.

Answer:

D. a decrease in predators
