Ecosystems

  1. 1. Ecosystems<br />Introduction to Biology<br />Mr. Brown<br />
  2. 2. Introduction<br />So what is an Ecosystem?<br />An Ecosystem is an environment consisting of all living and non-living things in a specific area.<br />
  3. 3. Where Are Ecosystems?<br />Everywhere. <br />Ecosystems are all around us. <br />
  4. 4. Common Types<br />The common types of ecosystems include Savanna, Coral Reef, Urban, Desert, Large-Marine, Forest, Prairie, Rainforest, and Tundra.<br />
  5. 5. Savanna<br />Savanna is a tall grassland ecosystem with small trees and shrubs. <br />There is a dry season and a wet season.<br />
  6. 6. Coral Reef<br />Coral Reef is an underwater structure made from calcium carbonate secreted by corals.<br />Often referred to as the rainforest of the sea<br />
  7. 7. Urban<br />Urban ecosystems are also cities and towns.<br />Large areas of land with lots of man made structures.<br />These structures include buildings, houses, and roads.<br />
  8. 8. Desert<br />Desert is a very hot and dry ecosystem.<br />The is very little plant and animal life in a desert.<br />The Ecosystem is too dry to support lots of life forms.<br />
  9. 9. Large-Marine<br />Large-Marine is large bodies of salt or fresh water.<br />2/3 of Earth is covered by large-marine.<br />Lots of plant and animal life.<br />
  10. 10. Forest<br />Forest a natural woodland area.<br />Two major types: Coniferous (cone-bearing) and Deciduous (leaf-bearing)<br />Lots of plant and animal life. <br />
  11. 11. Prairie<br />Prairie is a temperate grassland. <br />Little amounts of trees, but lots of other plants and animals.<br />Very moderate climate.<br />
  12. 12. Rainforest<br />Rainforest is a forest with lots of rainfall.<br />Very wet and rainy climate.<br />Very diverse, lots of plants and animal life.<br />40-75% of all species are indigenous to the rainforest.<br />
  13. 13. Tundra<br />Tundra is a cold and dry ecosystem.<br />Very icy and windy.<br />Very little plant and animal life .<br />
  14. 14. How Ecosystems Work<br />An ecosystem is a relationship between all living and non-living things in an area.<br />The flow of energy is vital to the success of an ecosystem.<br />Energy flow is also known as the food chain.<br />Food Chaindisplays whom eats whom in an ecological system.<br />
  15. 15. Endangered Ecosystem<br />Climate change is one problem destroying ecosystems.<br />The climate change problem is altering the specific climates in each ecosystem which causes many other environmental issues.<br />Another problem is natural resources.<br />Some ecosystems have lots of natural resources, and people are destroying the ecosystem to get to the natural resources.<br />
