Interactions Between Populations

Populations of organisms are often heavily influenced by their environments.  However, other populations within an environment can also have a large influence.  In the questions below, you will examine some of the ways in which populations can influence each other.

Questions

Please answer the questions below.

How might a change in the size of one population affect the amount of resources available in the forest for other populations?

Why might the change in the amount of resources available in the forest affect the size of other populations?

How might a change in the size of a population indirectly affect the size of another population in an ecosystem? For example, how do you think a change in the population of mice in a forest might affect the population of moths?
