Question

White-tailed deer live in forested areas and eat plants. Space is a limiting factor for all organisms. White-tailed deer in a forest ecosystem are using all of the space available in this ecosystem.

If there is a large increase in the amount of plants available in the area for the deer to eat, what will most likely happen to the population of white-tailed deer in this ecosystem?

Answer 1

It will increase at first, but the deer will become overcrowded, causing the population to decrease.

It will not change because food is not an important factor for population growth in deer.

It will increase forever because food is the only important need of an organism.

It will decrease immediately because the deer will stop eating plants and begin feeding on other animals.

The amount of shelter in an ecosystem is a limiting factor for population growth. A type of mouse lives in the forest and uses fallen trees for shelter. The mouse population has more food and water than its population needs.

If a storm blows through the area and knocks down many trees, what kind of effect will this most likely have on the population of mice?
The population will move to an Arctic area in order to find more shelter.

The population will decrease because of the increase in shelter available.

The population will not change because the mice will stopping using trees for shelter.

The population will increase because of the increase in shelter available.
