Food Webs and Biodiversity

1. Food Webs and Biodiversity

2. Producers • Most are photosynthetic • Use light energy to produce food • Some are chemosynthetic • Use stored chemical energy to produce food • All producers are Autotrophic • Produce their own food for energy

3. Producers Plants Algae

4. Consumers • Heterotrophic • Consume other organisms as food for energy • Herbivores-eat only plants • Carnivores-eat only meat • Omnivores- eat plants and meat

5. Consumers • Detritivores-receive energy from dead organisms • Decomposers-responsible for decay and returning nutrients back into environment

6. Trophic Level and Energy Pryamid Each organism represents a trophic level on the energy pryamid. Plants (Producers)

7. Energy Transfer Only 10% of the energy from one trophic level is transferred to the next.

8. Food Chain Shows how each living organism obtains food. What eats what. Primary Consumer Producer Secondary Consumer

9. Food Web Many food chains connected together

10. Biodiversity The diversity of life. The different organisms Found on the Earth.
