B
Steady rainfall increases the number of plants.
C
A spring freeze kills many plants.
D
The number of predators increases.
E
A harmful plant disease spreads through the area.
F
A harmful animal disease spreads among the population.

Explanation

A plant-eating animal population is limited when it has less food, faces more predators, or suffers from disease. A spring freeze that kills plants and a disease affecting plants reduce the animals’ food supply; more predators and a harmful disease among the animals also reduce their population. By contrast, fewer predators and more plants would generally help the population grow.
