At the bottom of every food chain are producers. They make up the backbone of life on earth. Without organisms that take energy from the sun and convert it to usable energy, where would all the other organisms, like us, get our energy? While many times it is indirect, all organisms, in part, rely on the sun for energy and in turn, for life.
The Sun is the main source of energy for organisms and the ecosystems of that they are a part. Producers such as algae and plants use energy in the from sunlight to form food energy by uniting carbon dioxide and water to form organic matter.
A food web defined as all the food chains in a single ecosystem. Each living thing in an ecosystem forms part of multiple food chains. Each food chain is one viable path through which energy and nutrients may take as they move through the ecosystem.
