What is the relationship between the carrying capacity and the population size in an ecosystem?

• Carrying capacity is always greater than the population size.

• Carrying capacity is always equal to the population size.

• Carrying capacity is always less than the population size.

• Carrying capacity can be greater than, equal to, or less than the population size.
