Deer are herbivores that feed on the small leaves of plants. What might happen if more deer move into an area?
The deer population will not change.
Small plants can become scarce, causing a decrease in the deep population.
Deer will learn to eat mice and rabbits.
Other plants will grow better.

A mushroom is growing on the stump of a dead tree. What could you infer about the role of the mushroom?
The mushroom is a producer, using the sun's energy to make its own food.
The mushroom is a decomposer, causing the stump to decay slower.

The diagram above shows a simple food web. What do you think would happen if the number of meat-eating fish decreased? Check all that apply.
The number of seals and sea otters will increase.
The organisms eaten by the meat-eating fish, plant-eating fish and shrimp and crab larvae, would increase.
The organisms eaten by the meat-eating fish, plant-eating fish and shrimp and crab larvae, would decrease.
The number of seals and sea otters will decrease.
Suppose many fish in the food web above died from disease. What would happen to the seal and water plant populations?
The number of seals and water plants would both increase.
The number of seals and water plants would both decrease.
The number of seals would increase and the water plants would decrease.
