Populations Day 4 Predator Prey Relationship

Multiple Choice

A population of kangaroos grows briefly and then stabilizes. What does the leveling off indicate?

• The population has reached the carrying capacity of the environment.

• The population has exceeded the carrying capacity of the environment.

• The population is affected by a density-independent limiting factor.

• The population is no longer able to adapt to environmental changes.

Multiple Choice

When a specific population grows past the ecosystem's carrying capacity, what happens to the population?

• Density Independent limiting factors start to occur resulting in the population going farther above carrying capacity.

• Density Dependent limiting factors start to occur resulting in the population going back below carrying capacity.

• The population will go extinct due to lack of resources

• The population grows then finds a new carrying capacity

Multiple Choice
