Beach ecosystems are a balance of living and non-living elements, which interact with each other

A beach ecosystem is a living community of plants and animals sharing an environment with non-living elements, such as water, sand and rocks.

Within the beach ecosystem, there are mutual dependence relationships across the whole system. All of the living things in the ecosystem rely on other things, both living and non-living, for their survival.

Food webs are one example of the interconnected nature of marine ecosystems.
