Joint Global Change Research Institute. Chair, GOFC-GOLD. Outline. The context of ecosystem services. . Table of Contents. Section 3: . Aquatic Ecosystems. Section 1: . How Ecosystems Change. Section 2: . Biomes. Chapter: Ecosystems. . Table of Contents. Section 1: . How Ecosystems Change. Mosses from my back yard. There are two main categories of freshwater ecosystems. What is the main . difference between. these two ecosystems? . Standing water . v. . flowing-water ecosystems. Standing water—staying still, not moving. Case Study. Key Dialogue Questions (KDQ). Should the lead sector for economic development be agriculture or industry, given that Ethiopia is a non oil-dependent developing country?. Should more priority be given to smallholder farms or private commercial farms, given the context of the agriculture sector of Ethiopia?. Living things need a place to live and grow.. . Fish live in water.. Birds live in trees and fly through the air.. Plants grow where there is soil, water and sun.. Main Idea and Details. ENVIRONMENT. Explain how biomes are characterized. Describe how net primary production varies among biomes. Explain how organisms are adapted to the conditions of their biomes. Describe the criteria ecologist use to classify aquatic systems. - Jacques Ives Cousteau. 2. New Orleans is nested between the mouth of the Mississippi River and the brackish estuary of Lake Pontchartrain.. 3. A series of floodwalls, or levees, protects the city from ocean surges from large storms.. 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.. Aquatic ecosystems are primarily determined by the ecosystem’s . salinity. . Salinity refers to the dissolved salt content of the water.. Aquatic ecosystems are divided into freshwater and marine ecosystems.. Section 3: . Aquatic Ecosystems. K. What I Know. W. What I Want to Find Out. L. What I Learned. Essential Questions. What are the major abiotic factors that determine the aquatic ecosystems?. What are transitional aquatic ecosystems and why are they important?. 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..
