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.

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