2. Food Chains show how energy moves through the ecosystem in a linear fashion.

3. Producer Primary Consumer Secondary Consumer Decomposer Food Chains show how energy moves through the ecosystem in a linear fashion.

4. Producer Primary Consumer Secondary Consumer Decomposer Food Chains show how energy moves through the ecosystem in a linear fashion. Autotroph (makes own food)

5. Producer Primary Consumer Secondary Consumer Heterotroph Decomposer Heterotroph Autotroph Heterotroph Eats something else Food Chains show how energy moves through the ecosystem in a linear fashion.

6. Producer Primary Consumer Secondary Consumer Carnivore omnivore Heterotroph Decomposer Heterotroph Autotroph Heterotroph Eats something else Green plant herbivore Bacteria & fungus Food Chains show how energy moves through the ecosystem in a linear fashion.

7. Producer Make 100%of food Primary Consumer Secondary Consumer carnivore Heterotroph Decomposer Heterotroph 10% Autotroph Heterotroph Eats something else Green plant herbivore decomposer Food Chains show how energy moves through the ecosystem in a linear fashion.

9. If you had a large population with limited resources to provide food… what would be the most efficient trophic level to feed them?

10. Producer Make 100%of food 100lbs. Primary Consumer 10% 10lbs. Secondary Consumer 1% 1lbs. carnivore Heterotroph Decomposer.1%.1lbs. Heterotroph Food Chains show how energy moves through the ecosystem in a linear fashion. 10% Autotroph Heterotroph Eats something else green plant herbivore decomposer heat

11. 4 Energy pyramids show how each trophic level (step in a food chain) is supported by the previous level..—;; ;;;;;;;; If the ecosystem has very few plants it can not have a lot of predators.
