Presentation Transcript

  1. Food Chains and Food Webs

  2. Why do scientists study food chains? • Scientists study food chains to see how energy flows through organisms • Where do we get energy? • Food (plants, animals) • Where do those organisms get energy?

  3. Carnivores

  4. Herbivores

  5. Omnivores

  6. Producers • Organisms that make their own food • Bottom of the food chain

  7. Consumers • Organisms that do NOT make their own food but have to find it • Primary consumers: middle of the food chain; get their energy from producers • Secondary consumers: top of the food chain; get their energy from primary consumers

  8. Decomposers • Breaks down the soft tissues of dead plants and animals • Two types of decomposers • 1. Bacteria • 2. Fungi

  9. Scavengers • Organisms that are too lazy to go hunt for their food

  10. Predators • Animals that hunt

  11. Prey • Animals being hunted

  12. Endangered • organisms that are rare and may eventually disappear

  13. Extinct • organisms that are gone

  14. How do humans affect food chains? According to Terracycle, 100 species of animals and plants become extinct every week!!!
