A food web is defined by the interlocking of food chains within an ecological community. In every food web, the sun is the main source of energy. If it wasn't for the sun, producers (such as plants) would not be able to go through photosynthesis.

In this food web, the acorns and the pine cones are the producers. The acorn passes its energy to the mouse (a primary consumer becuase it is a herbivore). The mouse takes 10% of the energy and passes it to the snake (a secondary consumer because it is an omnivore meaning it can eat meat or plants)or the hawk ( tertiary consumer because it is not eaten by anything in the food web). When any of these animals die, the decomposer (bacteria and fungi) break down the nutrients of the animal and recycle it back into the soil.
