Grade 7 Unit 06: Flow of Energy Review

1. 1. One of the products of photosynthesis is glucose. Glucose stores chemical energy. Where does the energy to create this molecule come from?
2. 2. Each trophic level is producing, or consuming energy for it's own purposes. It uses most of the energy in its daily activities. About how much energy from a trophic level is available to the next trophic level?
3. 3. What do the arrows in the food chain represent?
4. 4. What kind of energy transformation happens in photosynthesis?
5. 5. What kind of energy transformation happens when an animal breaks down sugars in order to move?
6. 
7. 6. How might the population of Vermilian Flycatchers be affected if there was a significant increase in the population of Trans-Pecos Ratsnakes?
8. 7. Draw a food chain from smilo grass to a Red-tailed Hawk.
