Food web
Show more interactions than in a food chain.
Usually leaves out decomposers cause things can get messy.
12
Energy pyramid
Shows two things.
It compares the population of each trophic (energy) level and shows the amount of energy in each trophic level.

Multiple Choice
14
Trophic levels
Only 10% of the energy of each trophic level actually makes it to the next level.
The other 90% is lost as heat to the environment.
15
