population dynamics & human impact

What is carrying capacity

• The minimum amount of individuals from a species that a habitat can hold

• The maximum amount of individuals from a species that a habitat can hold

• The amount of resources available at any given time

• The amount of resources used by animals

Which two things increase a population size

• Birth and emigration

• Death and immigration

• Birth and Immigration

• Death and emigration

What happens when a population overshoots its carrying capacity

• Nothing Happens

• More animals are born

• Each animal gets less resources to make room for more animals

• There are not enough resources to go around and some animals will die
