The Earth is home to many
different types of environments. While the vegetation and animal
life found in various locations may be different, the fundamental
relationships among organisms are the same everywhere.
The energy that sustains life
comes from the sun. The solar energy is converted to chemical energy
and flows from organism to organism.
In this Lesson, we'll look at
how energy flows through an ecosystem. We'll investigate the feeding
relationships of the organisms in an ecosystem, and see how they
help explain the ecosystem's energy flow. We'll also see how water
is recycled within and between ecosystems.
