3. Categorizing Animals and Plants Color Code the animals and plants Green= Producer (Produce their own food) Example: Shrub Yellow= Herbivore (Eat producers) Example: Rabbit Red= Carnivore (Eat Consumers) Example: Snake

4. Categorizing Animals and Plants Color Code the animals and plants Purple= Omnivore (Eat Producers and Consumers) Example: Birds Blue= Detritivores (Eats waste or dead material) Example: Vulture Gray= Decomposer (breaks down material) Example: Fungi and some bacteria

6. Food Web

7. Energy Flow Energy is needed to power life! Energy flows through the ecosystem.

8. Producers Organisms that make their own food without consuming another living organism are called producers. Also known as autotrophs

9. Producers: Photosynthesis Sunlight is the main source of energy for most ecosystems on Earth. Organisms use a process called photosynthesis to convert sunlight into energy.

10. Producers: Photosynthesis

11. Producers: Chemosynthesis Some ecosystems rely on energy obtained from organisms that store energy in inorganic chemical compounds. Organisms use a process called chemosynthesis to convert inorganic chemical compounds into energy.

12. Producers: Chemosynthesis

13. Consumers Organisms that cannot make their own food or energy have to consume (eat) other organisms. This organisms are called consumers. Also called heterotrophs.

14. Consumers: Herbivores Eat Producers (plants)

15. Consumers: Carnivores Eat consumers (meat)

16. Consumers: Omnivores Eat producers and consumers (plants and animals)

17. Consumers: Detritivores Eat dead organisms

18. Consumers: Decomposers Eat/break down decomposing material

19. Energy Flow Energy flows through an ecosystem in one direction from the sun or inorganic molecules to producers (autotrophs) and then to consumers (heterotrophs).

20. Food Chain Food Chain is a series of steps in which organism transfer energy by eating and being eaten.

21. Food Web Food Web is all of the feeding relationships among various organisms in an ecosystem.

22. Food Web Each step on a food web is a trophic level.

23. Ecological Pyramid An ecological pyramid is a diagram that shows the relative amounts of energy or matter contained at each trophic level of a food web.

24. Ecological Pyramid Only about 10% of the energy available within one trophic level is transferred to organisms at the next trophic level.
