Definition

Aquatic Ecosystem: is a “neighborhood” in which the creatures live and function a “liquid” (water) environment.

Hawaiian Translation: Kaiaola O Ka Wai (also term for fresh water ecosytem)


Example

In an ecosystem, plants and animals are interdependent. Plants, such as algae, produce food using energy from the sun to convert carbon dioxide and water into simple sugars. The algae is eaten by animals, such as fish and prawns. These animals are eaten by large birds, such as the Hawaiian stilt. A feeding relationship, where energy is transferred from green plants through a sequence of animals, is known as a food chain.
