Problem: An ecosystem is a biological community where living organisms, known as biotic factors, interact with their nonliving environment, or abiotic factors. In a North Carolina pond, for example, the frogs, insects, and microorganisms are biotic components that rely on abiotic elements like sunlight, temperature, and water to survive. The health of these populations is often governed by limiting factors-resources such as food, space, and shelter that restrict how many individuals can live in one area. When these resources are plentiful, a population can grow until it reaches its carrying capacity, which is the maximum number of organisms the environment can sustain over a long period without harmful effects.
