• It will decrease.

• It will increase.

• It will remain the same.

A scientist was studying a population of fish in a pond over a period of 10 years. He observed that

the population increased each year for 3 years, and then remained nearly constant for the rest of

the study. The best explanation for this observation is that the population had

• stopped reproducing

• reached carrying capacity

• mutated into a different species

• run out of food and all died

When a population grows past the ecosystem's carrying capacity, what happens to the population?
