A diagram that shows the transfer of energy from one organism to another (who is eaten by what).

Write the scientific term: 1. A diagram shows the amount of energy that moves from one feeding level to another in a food web. (............................) Put (true) or (false): 1. There is a limited number of levels in a food web or an energy pyramid. ( ) 2. Each level has less energy available in the energy pyramid than the level below. ( ) 3. Only about 50 percent of the energy at one level of a food web is available to the next higher level. ( ) 4. Producers can be found at the base of the energy pyramid. ( )

Energy in a food chain starts with energy from the which is turned into chemical energy by .  This energy is transferred to as they eat the plants.
