The document discusses the flow of energy through ecosystems via an energy pyramid. It explains that energy from the sun is transferred to plants, then to smaller animals, then to bigger animals, and finally the largest animals. As the energy moves through the food chain, each animal uses most of the energy for itself and passes on only a small amount, resulting in less available energy at each higher level of the pyramid. An energy pyramid illustrates how the amount of energy remaining decreases as it moves through a food chain or web in an ecosystem.

2. Energy Pyramid
Energy moves through an
ecosystem from the sun, to
plants, to smaller animals, to
bigger animals, to the
biggest animals.

uses most of it’s energy and
passes on only a small

7. Energy Pyramid
Bottom level is the
producers and contains
most energy
 As you go up it is narrower less energy and fewer living
things.
