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

Which of the following choices represents a reason that the seal population has reached its carrying capacity?

• The seals ran out of available resources (food, nutrients, etc.)

• The seals were living in an area that had less predators.

• The seals are at the top of their food chain.

• The seals are keystone species.
