Food Webs

• The organization of communities is based on the utilization of the energy from the sun within a given ecosystem. The greatest amount of energy in a community is in the producers.
• Within a community, organisms are dependent on the survival of other organisms. Energy is passed from one organism to another.
• The organization of a community is defined by the interrelated niches within it.
• The sun’s energy cycles through ecosystems from producers through consumers and back into the nutrient pool through decomposers.
• A niche is the function that an organism performs in the food web of that community. A niche also includes everything else the organism does and needs in its environment. No two types of organisms occupy the exact same niche in a community.
