  1. I. Ecology

  2. A. What is Ecology? 1. Ecology is the study of interactions among organisms and their environments. • Basically: The Discovery Channel!

  3. Abiotic Non-living factors Biotic Living Factors B. Ecology Terms Note: Adding an “a” prefix makes the word mean the opposite. Ex: Muse = to think, Amuse = to not think

  4. C. Levels of Organization • Organism • Population • Community • Ecosystem • Biosphere

  5. Organism Organism Levels of Organization • Organism - individual living thing, such as an alligator.

  6. Population Population Organism Organism Levels of Organization • Populations – groups of individuals that belong to the same species and live in the same area.

  7. Community Community Population Population Organism Organism Levels of Organization • Communities – assemblages of different populations that live together in a defined area.

  8. Ecosystem Ecosystem Community Community Population Population Organism Organism Levels of Organization • Ecosystems – collection of all the organisms that live in a particular place, together with their nonliving, or physical, environment.

  9. Biome Ecosystem Ecosystem Community Community Population Population Organism Organism Levels of Organization • Biomes – group of ecosystems that have the same climate and similar dominant communities.

  10. II. Energy in Ecology

  11. A. Producers • Autotrophs • Food from self

  12. Heterotrophs Food from others B. Consumers • Herbivores • Eat plants • Carnivores • Eat animals • Omnivores • Eat both • Detritivores • Eat dead matter

  13. C. Food Chains • Shows how matter and energy move through an ecosystem • Arrow points toward the belly of the consumer.

  14. D. Food Webs • Shows how matter and energy move through an ecosystem

  15. E. Trophic Levels • The passage of energy and materials from one organism to another. • Only 10% is passed on!

  16. F. Ecological Pyramids • An ecological pyramid is a diagram that show the amount of energy or matter contained with each trophic level of a food chain or food web

  17. Homework • Levels of Organization WSs
