Energy Flow
Watch the energy flow video clip and answer the following
questions.
1.
What is an abiotic factor? Give an example of an abiotic
factor related to the flow of energy in a food chain.
2.
Draw the Energy Pyramid. Define the “trophic levels” (feeding
levels).
3.
How much energy is transferred from one trophic (feeding)
level to the next trophic level?
4.
How much energy is not passed on from one level to the next?
Where does this energy go?
5. Define biomass. How much decrease in biomass is there
between each trophic level? On the flip side, how much biomass is
moved on between the levels?
6. Why is the producer the largest level?
