How do organisms affect one another’s survival and environment?

What happens without predators?

With no predators to control the population and alter feeding behavior, the prey species quickly degrade and over-run its habitat. As food becomes scarce, the population becomes sick and malnourished, and will either move or crash.

How does the community and habitat affects the ecosystem?

The community of living (biotic) things interacts with the nonliving (abiotic) world around it to form the ecosystem. The habitat must supply the needs of organisms, such as food, water, air, and space to grow. If the population’s needs are not met, it will move to a better habitat or die.
