There are usually no more than four trophic levels in a food chain. Why?

• Energy gets lost (metabolism) and too many links cannot be supported.

• Energy is gained (metabolism) and too many links cannot be supported.

• There are not very many animals on earth.

• Scavenger

• Carnivore

• Herbivore

• Decomposer

An energy pyramid shows the loss of energy at each trophic level. Why is energy not really lost?

• Some energy is converted into waste and heat energy.

• Some energy goes back to the sun.

• Some energy is recycled.

• All energy gets transfered to the next organism.
