  10. 10. Today’s Objectives Define ecosystem, biotic factor, abiotic factor, organism, species, population, community, habitat. Distinguish between the biotic and abiotic factors in an ecosystem. Describe how a populations differ from species. Explain how habitats are important for organisms.
  11. 11. Warm Up (Feb. 22)1. What are two of the most interesting facts that you’ve learned from the research information gathered for your project?3. How does your system relate to one of the other three?5. What’s one of the most valuable skills you’ve learned while completing your project?
  12. 12. Defining an Ecosystem• Ecosystems are communities of organisms and their abiotic environment. – Examples are an oak forest or a coral reef. – Ecosystems do not have clear boundaries. – Things move from one ecosystem to another. • Pollen can blow from a forest into a field, soil can wash from a mountain into a lake, and birds migrate from state to state.
  13. 13. What Does an Ecosystem Need To Survive?• In order to survive, ecosystems need five basic components: energy, mineral nutrients, water, oxygen, and living organisms.• Most of the energy of an ecosystem comes from the sun.
  14. 14. Biotic and Abiotic Factors• Biotic factors are environmental factors that result from the activities of living organisms such as plants, animals, dead organisms, and the waste products.• Abiotic factors are environmental factors that result from nonliving features such as air, water, rocks, and temperature.
  15. 15. Quick Exercise Take 2 minutes to two list of all the abiotic and biotic features that you see in this picture.
  16. 16. The 4 Major Levels of Ecological Organization• The four major levels of ecological organization are:  organisms  species  populations  communities
  17. 17. The 4 Levels of Ecological Organization • Organisms are living things that can carry out life processes independently. • Species are groups of organisms that are closely related and can mate to produce fertile offspring.
  18. 18. The 4 Levels of Ecological Organization • Populations are groups of organisms of the same species that live in a specific geographical area and interbreed. • Communities are groups of various species that live in the same habitat and interact with each other.
  19. 19. What is a Habitat?• Habitats are places where an organism usually lives.• Every habitat has specific characteristics that the organisms that live there need to survive.• In fact, animals and plants usually cannot survive for long periods of time away from their natural habitat.
  20. 20. Wrap Up (Feb. 22)) List the correct order of the 4 levels of ecological organization.i How are habitats important for organisms? Where does most of the energy in an ecosystem come from?
