  1. 1. Ecosystems<br />
  2. 2. What is an Ecosystem?<br />Biological Environment<br />Consists of Organisms<br />Live in a particular area<br />Includes Non-living organisms<br />Physical Components of the Environment<br />Organisms Interact <br />
  3. 3. Population<br />What is a population?<br />All the organisms<br />Belong to same species<br />Live in the same geographical area<br />
  4. 4. Community<br />What is a community?<br />Group of interacting species<br />Share a populated environment<br />Include living and non-living organisms<br />
  5. 5. Interactions<br />Organisms interact in various ways<br />May be beneficial<br />Shelter, Food, Safety<br />May not be beneficial<br />Harmful to the organism<br />Harmful to <br /> other organisms<br />
  6. 6. Biotic Factors<br />Living Organisms<br />Plants<br />Animals<br />Fungi<br />Protista<br />Bacteria<br />
  7. 7. Abiotic Factors<br />Non-living Organisms<br />Affect living organisms<br />Environmental factors such as habitat<br />Pond, lake, ocean, desert, mountain<br />Weather Factors<br />Temperature, cloud cover, rain, snow hurricanes<br />
  8. 8. What is a Food Chain?<br />Shows how each living thing gets food<br />Starts with Sun/plant life<br />Ends with an animal <br />
  9. 9. Consumers<br />Cannot make their own food<br />Feed on other plants/animals<br />Three types of consumers:<br />Herbivores- Eat only plants<br />Carnivores- Eat other animals<br />Omnivores- Eat both plants and animals<br />
  10. 10. Producers and Decomposers<br />Producers <br />Plants<br />Use light energy from sun <br />Produce food from CO2 and Water <br />Decomposers<br />Bacteria and fungi- Feed on decaying matter.<br />
  11. 11. Food Web<br />Shows all feeding relationships<br />between organisms living in an ecosystem<br />More complex the a food chain<br />More accurate then food chains<br />Several food chains joined together<br />Organisms depend on more than one species for food<br />
  12. 12. Food Web Cont.<br />
  13. 13. Environmental Changes<br />Land-Use Change<br />Storm Severity<br />Species Behavior<br />Population Growth Rate<br />Evolution <br />
  14. 14. Great Lakes Region<br />Sand dunes, coastal marshes, rocky shorelines<br />Lake plain prairies, savannas, forests<br />Four Seasons<br />Summer and Fall<br />Spring and Winter<br />Great Beaches<br />
  15. 15. Food Web Assignment<br />Create your own food web<br />Worth 10 points<br />Must consist of at least 10 organisms<br />Must be Accurate<br />Be creative<br />Have fun with it!<br />
