This lesson utilizes the example of healthy estuaries to demonstrate tools scientists use to measure ecosystem health. Students will learn the definition and function of an estuary, an essential coastal ocean ecosystem. Students will then learn methods to measure parameters of large areas using quadrats and subsets. . Getting started. With this GEO resource you will be learning about the location and biodiversity of . coral reefs. , their value to us and the environment and threats affecting global reefs today. We will also investigate the response to such threats in term of management.. (A) . Abiotic. component. (B) Biotic component. Abiotic. component:.
