Some source of "energy" is needed for all organisms to stay alive and
grow.

Food provides molecules that serve as fuel and building material for
all organisms. Plants use the energy from light to make sugars from carbon
dioxide and water. This food can be used immediately or stored for later
use. Organisms that eat plants break down the plant structures to produce
the materials and energy they need to survive. Then they are consumed by
other organisms.

The chemical elements that make up the molecules of living things pass
through food webs and are combined and recombined in different ways. At
each link in a food web, some energy is stored in newly made structures
but much is dissipated into the environment as heat. Continual input of
energy from sunlight keeps the process going.
