1. Ecosystems

2. What is an Ecosystem? Biological Environment Consists of Organisms Live in a particular area Includes Non-living organisms Physical Components of the Environment Organisms Interact

3. Population What is a population? All the organisms Belong to same species Live in the same geographical area

4. Community What is a community? Group of interacting species Share a populated environment Include living and non-living organisms

5. Interactions Organisms interact in various ways May be beneficial Shelter, Food, Safety May not be beneficial Harmful to the organism Harmful to other organisms

6. Biotic Factors Living Organisms Plants Animals Fungi Protista Bacteria

7. Abiotic Factors Non-living Organisms Affect living organisms Environmental factors such as habitat Pond, lake, ocean, desert, mountain Weather Factors Temperature, cloud cover, rain, snow hurricanes

8. What is a Food Chain? Shows how each living thing gets food Starts with Sun/plant life Ends with an animal

9. Consumers Cannot make their own food Feed on other plants/animals Three types of consumers: Herbivores- Eat only plants Carnivores- Eat other animals Omnivores- Eat both plants and animals

10. Producers and Decomposers Producers Plants Use light energy from sun Produce food from CO2 and Water Decomposers Bacteria and fungi- Feed on decaying matter.

11. Food Web Shows all feeding relationships between organisms living in an ecosystem More complex the a food chain More accurate then food chains Several food chains joined together Organisms depend on more than one species for food

12. Food Web Cont.

13. Environmental Changes Land-Use Change Storm Severity Species Behavior Population Growth Rate Evolution

14. Great Lakes Region Sand dunes, coastal marshes, rocky shorelines Lake plain prairies, savannas, forests Four Seasons Summer and Fall Spring and Winter Great Beaches

15. Food Web Assignment Create your own food web Worth 10 points Must consist of at least 10 organisms Must be Accurate Be creative Have fun with it!
