Interactions in Ecosystems
The life processes of plants and animals are interdependent and contribute to the flow of energy and cycles of matter within an ecosystem. One example of this is the water cycle.

Water Cycle by LUTFI GANI AL ACHMAD from NounProject.com
The interactions and organization within an ecosystem is based on the utulization of energy from the sun. The greatest amount of energy in an ecosystem is in the producers.
Food Chains
Animals cannot make their own food but plants can. Energy is transferred from plants to animals and continues though each animal that is eaten by another animal (see example below).
