Multiple Choice

Population density can be best described as:

• The amount of individuals in a given space.

• The amount of available nutrients in an ecosystem

Multiple Choice

In a given area, if the population of predators increases, the population of prey will _____________.

Multiple Choice

Emigration is:

• Eradication

Multiple Choice

A density-dependent limiting factor only becomes limiting if:
