Energy flow: food webs and trophic pyramids — Homework
Check every food chain you build by asking "does this organism really eat that one?"
- 1.Arrange into a valid chain: hawk, seeds, mouse, snake.
- 2.A pond has 25,000 kcal stored in algae (producers). How much energy is available to secondary consumers (two levels up)?
- 3.Explain why a food web is a more realistic model than a single food chain.
- 4.Explain, using only energy math (no opinions), why eating lower on a food chain supports more people per acre of farmland than eating higher on it.
- 5.Describe a food web with at least four organisms and two trophic levels, based on something in your own neighborhood.
