Trophic Levels Worksheet
You've learned today about the transfer of energy between different trophic levels of a food chain. Now you get to be the ecologist. You've been investigating a food chain in Morgan County ("Go With Da Flow" Worksheet) and you want to understand the flow of energy through this chain.

Ecology Worksheet # 2/AP Biology Name _____ 1. Interdependence in nature is illustrated by the transfer of energy through trophic levels.
Pyramid Diagrams •Trophic levels are arranged with the producers at the base of the pyramid and the consumers in increasingly higher levels up the pyramid •The width of the pyramid at any trophic level indicates the size of the standing crop.
2 level therefore contains only 10% of the energy in the next lower trophic level. Most ecosystems are thereby limited to five or fewer trophic levels.
General Ecology (BIO 160) Dept. of Biological Sciences Worksheet #16 Sacramento State University Worksheet 16: ... energy moves up the different trophic levels from primary producers (autotrophs) to herbivores (primary consumers) to carnivores (secondary and tertiary consumers).
By showing the trophic (feeding) levels of the ecosystem, students can easily visualize how energy is transferred from producers to consumers.
Eating at Lower Trophic Levels: Answer Key 1. Grasshoppers a hen needs per year 2. How many grasshoppers are needed for a year's supply of hens for a farmer each year?
About 90% of the energy is lost, therefore only 10% remains in the subsequent trophic level. 2. Thus as the trophic levels increase, the amount of energy and biomass decreases, ...
