This is an educational powerpoint about ecosystems.

1. Ecosystems Introduction to Biology Mr. Brown

2. Introduction So what is an Ecosystem? An Ecosystem is an environment consisting of all living and non-living things in a specific area.

3. Where Are Ecosystems? Everywhere. Ecosystems are all around us.

4. Common Types The common types of ecosystems include Savanna, Coral Reef, Urban, Desert, Large-Marine, Forest, Prairie, Rainforest, and Tundra.

5. Savanna Savanna is a tall grassland ecosystem with small trees and shrubs. There is a dry season and a wet season.

6. Coral Reef Coral Reef is an underwater structure made from calcium carbonate secreted by corals. Often referred to as the rainforest of the sea

7. Urban Urban ecosystems are also cities and towns. Large areas of land with lots of man made structures. These structures include buildings, houses, and roads.

8. Desert Desert is a very hot and dry ecosystem. The is very little plant and animal life in a desert. The Ecosystem is too dry to support lots of life forms.

9. Large-Marine Large-Marine is large bodies of salt or fresh water. 2/3 of Earth is covered by large-marine. Lots of plant and animal life.

10. Forest Forest a natural woodland area. Two major types: Coniferous (cone-bearing) and Deciduous (leaf-bearing) Lots of plant and animal life.

11. Prairie Prairie is a temperate grassland. Little amounts of trees, but lots of other plants and animals. Very moderate climate.

12. Rainforest Rainforest is a forest with lots of rainfall. Very wet and rainy climate. Very diverse, lots of plants and animal life. 40-75% of all species are indigenous to the rainforest.

13. Tundra Tundra is a cold and dry ecosystem. Very icy and windy. Very little plant and animal life .

14. How Ecosystems Work An ecosystem is a relationship between all living and non-living things in an area. The flow of energy is vital to the success of an ecosystem. Energy flow is also known as the food chain. Food Chaindisplays whom eats whom in an ecological system.

15. Endangered Ecosystem Climate change is one problem destroying ecosystems. The climate change problem is altering the specific climates in each ecosystem which causes many other environmental issues. Another problem is natural resources. Some ecosystems have lots of natural resources, and people are destroying the ecosystem to get to the natural resources.
