Final answer:
Negative feedback loops primarily maintain ecosystem stability by counteracting changes and disturbances in the ecosystem.
Step-by-step explanation:
Negative feedback loops primarily maintain ecosystem stability. Negative feedback loops work to counteract any changes or disturbances in an ecosystem, helping to maintain a stable balance. For example, if there is an increase in the population of a predator species, the increase in predation will eventually lead to a decrease in the prey species population, which will then cause a decrease in the predator population. This negative feedback loop helps maintain balance in the ecosystem.
