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.

What causes competition to occur in an environment?

• Good conditions make resources plentiful.

• Organisms struggle for a limited resource.

• Members of a population have different roles.

• A population falls below the environment’s carrying capacity.

Carrying Capacity is

• the capacity of what one person can carry per day 
• how many animals you have in your daily bag limit at the end of the year
• wildebeest at a watering hole with zebras
• the maximum number of individuals that the environment can support
