  1. Food Chains and Energy Pyramids By: Brianna Shields November 1, 2004

  2. DO NOW • 1. Which biome is cold, has flat, bare land, few plants and animals, and permafrost? • 2. What makes up a community? • 3. What makes up a population?

  3. GOAL • To understand energy flow through food chains, food webs, and energy pyramids

  4. Energy 1. Produced by sun 2. Needed by all living things 3. Animals obtain energy by eating plants Food Chains

  5. Food Chain Energy passed between living things through food Food Chains

  6. Food Web Several overlapping food chains Food Chains

  7. Predator An animal that eats other animals for food - “hunter” Food Chain Members

  8. Prey An animal eaten by a predator Food Chain Members

  9. Herbivore Animals that eat only plants Food Chain Members

  10. Carnivore Animals that eat other animals (meat) Food Chain Members

  11. Omnivore Animals that eat plants and other animals Food Chain Members

  12. Producer Organisms that make their own food (plants) Food Chain Members

  13. Consumer Living things that don’t make their own food Food Chain Members

  14. Autotroph Producer (plant) Food Chain Members

  15. Heterotroph Consumer (animals, fungus) Food Chain Members

  16. Decomposer Organisms that break down dead organisms ex: fungus, bacteria Food Chain Members

  17. Sample Food Chain

  18. How would you label the members of this food chain? • Sun---> grass----> rabbit--->hawk-->fungus Producer Autotroph Consumer Heterotroph Herbivore Consumer Heterotroph Carnivore Consumer Heterotroph Decomposer Energy Source

  19. Consumer Heterotroph Carnivore How would you label the members of this food chain? What members are missing? Consumer Heterotroph Carnivore Consumer Heterotroph Herbivore Producer Autotroph

  20. Create a food chain with the following organisms: • Field mouse, sun, bobcat, bacteria, snake, clover • Sun--> clover--> field mouse--> snake--> bobcat---> bacteria

  21. Energy Pyramid 1. Sun holds 100% of available energy 2. The farther up the food chain you go, the more energy is lost to heat and activity 3. So, the higher you go, the lower the amount of available energy Energy Pyramids

  22. Energy Pyramid

  23. Energy Pyramid

  24. Energy Pyramid- Label the food chain members. Where is the most energy found- why?

  25. Assessment
