Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment" (. . Hua. Chen.

By Renee Swank. In this activity you will learn all about the types of ecosystem. You can read all of the material and watch a short video on ecosystems. After you have read the material and watched the video, you can take the short quiz to see how much you learned!!. Pantelleria. .  .                       . Click on the Biomes to learn more!!. Grassland. M. arine. Tundra. Forest. Fresh Water. Desert. Desert Biome. This biome is the driest; it only receives 50cm of rainfall a year about 10% of the rainfall in the rainforest. Its plants and animals have to survive in an environment with little water and dramatic temperature changes from day to night. Some animals and plants may find if difficult to adapt, but reptiles and cacti thrive in these conditions.. 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.. http://www.neok12.com/php/watch.php?v=zX0215667004445d05420545&t=Ecosystems. Why do we find different plants and animals in different biomes?. Plants and animals are adapted to live in their biome. They live within that certain climate.. Chapter 3 (Miller and . Spoolman. , 2010). Core Case Study: Tropical Rain Forests Are Disappearing. Cover about 2% of the earth’s land surface. Contain about 50% of the world’s known plant and animal species. A BIG group of LIVING things . Different kinds of species. Large geographical area/ REGION. How are biomes commonly identified?. Biomes are commonly identified by the Biome’s dominant . plant species. The . altiplano. is a high plateau in the Andean regions of two South American nations.. The . varzea. , or “flooded forest,” is found mainly along the Amazon River in this nation.. The . cerrado. 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 Santa Monica Mountains National Recreation Area.

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.. 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.
