MY MUDDIEST POINT!

My muddiest point is probably the food wed. One is that I don't really get how the energy gets lost by going up and I didnt get the question # 15 on the Ecology quiz: In the food web, the majority of the energy which entered the ecosystem did not make it to the shark. What happened to that engergy? I got confused by the question. Can anyone help me?

    Good question!!!

    As organisms use energy, the energy gets converted into a different form. Cells use CHEMICAL energy (that's what food is). When cells use that energy to do work, the energy gets CONVERTED into heat energy.

    Remember... energy cannot be destroyed. Energy can not be created. It gets converted. And in living things, the energy gets converted into heat. The heat then just disapates into the air.
