1. Biology EOC: Trophic Levels
analyze the flow of matter and energy through trophic levels using various models, including food chains, food webs, and ecological pyramids

2. #7

3. Trophic Levels=Energy Levels
Each Level In A Food Chain, Food Web, or Ecological Pyramid.
It all begins with the SUN
Producers: Plants produce food through photosynthesis.
Trophic Level #1

4. Each level depends on the one below it for energy.
Primary Consumers:
2. Herbivores (Eat Plants)
Trophic Level #2
Secondary Consumers:
3. Carnivores (Eat Herbivores) & Omnivores (Eat Plants and Animals)
Each level depends on the one below it for energy.

5. Label the pyramid with the following terms:
Ecological Pyramid:
Label the pyramid with the following terms:
Most Energy
Least Energy
Most Biomass
Least Biomass
Primary Consumer
Producer
Tertiary Consumer
Secondary Consumer 4 3 2 1

6. Ecological Pyramid Only 10% of the potential energy
is available as you move
up each level.

7. Food Chain Simple Energy path through an ecosystem

8. Name the Producers, Primary Consumer, Secondary Consumer, & Decomposers in this food chain:

9. Food Web:
More realistic path through an ecosystem made of many food chains

11. How Many Chains are in this web?

12. Competition:
Predation:
Parasitism:
Mutualism:
Commensalism:
