Why can many ecosystems exist in one biome

An ecosystem is a biological community of oranisms with the living and non living parts of their environment. A biome is a community of all of the animal life of a particular region. With this in mind a a biome is made up of many different ecosystems. In addition, because these ecosystems make up a biome they interact and benefit one another.

Numerous ecosystems systems can exist in one biome in light of the fact that a biome is immense, and take the Marine Biome for example. There are diverse zones that things live in or environments. There are environments appropriate by the shore, somewhat more distant, and one ideal amidst the water. So there can be numerous in one biome in light of the fact that a biome is only one class, similar to tundra, or marine.
