INTRODUCTION Biosphere reserves are areas of terrestrial and coastal/marine ecosystems, or a combination thereof, which are internationally recognized within the framework of UNESCO's Programme on Ma Unit 1: . Intro to Environmental Science. What is environmental science? . In a group of 2 or three, write as many words as you can think of that come to your mind when you think of “Environmental Science”. Overview: Discovering Ecology. Ecology. is the scientific study of the interactions between organisms and the environment. These interactions determine distribution of organisms and their abundance. 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. 0 34.7 Current, sunlight, and nutrients are important abiotic factors in freshwater biomes Freshwater biomes cover less than 1% of the Earth, contain less than 0.01% of its water, harbor 6% of all described species, and Dr. .

Biomagnification. is the process by which matter becomes concentrated in living things in a food chain.. Moving up the Food Chain . DDT provides one example of the effects of . biomagnification. in an ecosystem. DDT is a chemical that was widely used to kill plant–eating insects. Some chemicals break down over time, but DDT does not. DDT collected in water and soil, was absorbed by living things, and moved up the food chain. The diagram shows how DDT became magnified in a wetland ecosystem. It entered through tiny organisms called zooplankton, which absorbed DDT from the water.. Rahil Alhumaidi. October/10/2013. B-2.
