• exceeds the habitat’s carrying capacity.
• is competing with another species.
• grows increasingly faster.
• breeds with another species.

A population is...

• A group of one species in one area
• Multiple species that live in one area
• All of the living and nonliving things in an area
• None of these

Which kind of dispersion is #1?

• clumped
• random
• uniform

What will happen to the population when the death rate is larger than the birth rate?

• grow
• shrink
• stay the same
• None of these

What will happen to the population when the birth rate is larger than the death rate?

• grow
• shrink
• stay the same

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

• Continues to grow
• The population starts to die off to return to carrying capcity
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity
