Question

the sunfish population in a local lake was monitored over several years. what limiting factor is most likely responsible for the change occurring at point x in the graph? decreased predator population increased sunlight availability decreased food supply increased water levels

Explanation:

At Point X, the population density reaches a peak and then starts to decline. A decreased food supply is a limiting factor that would cause the population to decrease as it can no longer support the high number of individuals. A decreased predator population would likely cause the sunfish population to increase further. Increased sunlight availability and increased water levels (assuming they are within a beneficial range) would likely support the population rather than cause a decline.

Answer:

decreased food supply
