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

What happens to a population when it exceeds its carrying capacity?

• It stabilizes at a higher level

• It continues to grow indefinitely

• It decreases due to resource depletion

• It remains unaffected
