A population is 

• a group of communities that exist in different places
• a group of organisms of one species that lives in the same area at the same time
• a group of people that populate one place at the same time on different planets

Owls and snakes eat mice and other organisms. What would happen to the mice population if the owl population decreased?

• The population would decrease, as the loss of owls as part of their diet is a limiting factor.

• The population would decrease, as shelters created by owl nests is a limiting factor.

• The population would increase, as competition for food is a limiting factor.

• The population would increase, as predation by owls is a limiting factor.

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
