Ecology Review

  1. 1. Ecology Review Chapter 5, Lessons 1-6
  2. 2. Organisms <ul><li>An organism is any living things. </li></ul><ul><ul><li>This includes plants, animals, bacteria, and even fungi. </li></ul></ul><ul><ul><li>All organisms are also biotic. </li></ul></ul><ul><li>Can you list some organisms that you know of? </li></ul>
  3. 3. Populations <ul><li>Many populations make up the living parts of an ecosystem. </li></ul><ul><li>A population is a group of organisms of one species that live in an area at the same time. </li></ul><ul><li>A population may be all the pine trees or all the squirrels in an area. </li></ul>
  4. 4. Community <ul><li>A community is made up of all the populations in an area. </li></ul><ul><li>Members of a community depend on each other to fill needs, such as food and shelter. </li></ul><ul><li>In other words, a community is all the living things in an area and they all depend on each other. </li></ul>
  5. 5. Organism Population Community
  6. 6. Biomes <ul><li>A biome is a large ecosystem with generally the same climate and organisms. </li></ul><ul><li>All the biomes together create the biosphere . (The part of Earth in which all living things are located.) </li></ul><ul><li>There several types of biomes. </li></ul>
  7. 7. Types of Biomes
  8. 8. Habitats <ul><li>A habitat is the place in which an organism lives. </li></ul><ul><ul><li>Made up of the soil, air, and water, as well as the plants of the area. </li></ul></ul><ul><ul><li>What is your habitat made up of? </li></ul></ul><ul><li>A niche is the role or job of a specific organism. </li></ul><ul><ul><li>Each organism has a specific niche. </li></ul></ul><ul><ul><li>The niche of a spotted owl in his habitat is that of a hunter. </li></ul></ul><ul><ul><li>What is the niche of a mushroom? </li></ul></ul>
  9. 9. Name the Niche
  10. 10. Food Chains <ul><li>A food chain is the transfer of energy through a series of organisms that use each other as food. </li></ul><ul><ul><li>Producers: organisms that make their own food. </li></ul></ul><ul><ul><li>Consumers: organisms that get their food from eating other organisms. </li></ul></ul><ul><ul><ul><li>Herbivores: eat only plants. </li></ul></ul></ul><ul><ul><ul><li>Omnivores: eat plants and animals. </li></ul></ul></ul><ul><ul><ul><li>Carnivores: eat only animals. </li></ul></ul></ul>
  11. 11. Food Webs <ul><li>A food web is all the food chains in a particular place tied together. </li></ul>
  12. 12. Energy Pyramids <ul><li>An energy pyramid is a diagram that shows the amounts of energy that flows through each level of a food chain. </li></ul><ul><li>Example: </li></ul><ul><ul><li>Plants get energy from the sunlight. They store some of it. </li></ul></ul><ul><ul><li>Hares (herbivores) get energy from the plants. Only a small amount of this energy is stored. </li></ul></ul><ul><ul><li>Owls get energy from eating animals. Only a small fraction of this energy is stored. </li></ul></ul>
  13. 14. Cycles <ul><li>A cycle is a repeating process or flow of material through a system. </li></ul><ul><ul><li>Nitrogen Cycle </li></ul></ul><ul><ul><li>Carbon/Carbon Dioxide Cycle </li></ul></ul>
  14. 15. Nitrogen Cycle
  15. 16. Carbon Cycle
