Energy is all around you. Learn about the many different types of energy and how energy can change form. Vivid examples illustrate how potential energy and kinetic energy are defined, and how one form of energy can change into another. Discover that energy never goes away, that it can only be transferred from one form into another.

Any ecosystem needs energy to sustain it, and the organisms within it. This energy comes in massive quantities from the Sun, although only a tiny fraction of the solar energy hitting the Earth goes towards sustaining life. The flow of energy through an ecosystem is complex, and vital to sustaining all life within it.
