carrying capacity
peak
perfect balance
trough
rewatch

Explanation:

The carrying capacity is the maximum number of individuals of a species that an environment can support indefinitely given the available resources like food, water, and space. When a population exhausts these resources (runs out of food or space), it has reached its carrying capacity. A peak is just a high point in a population - related graph (like a business cycle peak which is different from this ecological concept). Perfect balance is a very vague term and not a standard ecological term for this context. A trough is a low point (opposite of a peak in non - ecological contexts like business cycles).

Answer:

carrying capacity
