CHAPTER. Too Much of a Good Thing?. Elephant populations in southern Africa declined sharply due to hunting but have made overwhelming comebacks within nature reserves and parks.. Some worry that elephant overpopulation is causing a decline in local biodiversity and damage to farms and infrastructure.. Environmental Literacy Project. Michigan State University. . Ecosystems .

An ecosystem is a group of living and nonliving things in a place that has a specific climate, landforms, soil types, and vegetation. . Summary. 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. . Unit Standards. 5.L.4A.1 . Analyze and interpret data to summarize the abiotic factors (including quantity of light and water, range of temperature, salinity, and soil composition) of different terrestrial ecosystems and aquatic ecosystems. . 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:. Abiotic. component of pond consists of water, dissolved minerals, oxygen and carbon dioxide. Solar radiations are the main source of energy.. Getting started. You’ll need a notepad on which to make notes as you go along, or you could make notes, paste images, etc. on your device.. You can view these slides:. as a slide-show for any animations and to follow links.
