A food web (or food cycle) is the natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community. Another name for food web is consumer-resource system. ... Some of the organic matter eaten by heterotrophs, such as sugars, provides energy.
Because biomass decreases with each trophic level, there are always more autotrophs than herbivores in a healthy food web. ... A healthy food web has an abundance of autotrophs, many herbivores, and relatively few carnivores and omnivores. This balance helps the ecosystem maintain and recycle biomass.N
