  1. Ecosystem Dynamics

  2. Trophic levels Producers- Organisms that “produce” their own energy Autotrophs- Organisms capable of “feeding themselves” (via photosynthesis) • Levels of feeding in an environment • Illustrate the flow of energy in an environment Consumers- Organisms that consumer other organisms to obtain energy Heterotrophs- Organisms that eat other things for energy 1° consumer- Organism that occupies the first consumer level above producers Herbivore- Organism that obtains all of its energy by eating plant matter 2° consumer- Org. that occupies the second consumer level above producers Omnivore? Org. that obtains its energy by eating both plant and animal matter 3° consumer- Org. that occupies the third consumer level above producers Carnivore- Org. that obtains its energy by eating only animal matter 4° consumer- Org. that occupies the fourth consumer level above producers Carnivore- Org. that obtains its energy by eating only animal matter

  3. Reduction in individuals And BIOMASS Loss of energy 4° consumer 3° consumer 2° consumer 1° consumer Producers (autotrophs)
