0 an animal that eats plants and therefore changes the energy from the sun that is stored in plants into meat that can be eaten by other animals --
Donor controlled food webs may be inherently more stable, because it is difficult for primary consumers to overtax their resources.
Primary consumers have longer lifespans and slower growth rates that accumulates more biomass than the producers they consume.
The organisms that consume their tissues are called primary consumers or secondary producersherbivores.
Primary consumers are usually herbivores, feeding on plants and fungus.
Larger organisms, such as snails, shrimp, crabs, tube worms, fish, and octopi, form a food chain of predator and prey relationships above the primary consumers.
Then come the primary consumers, such as grasshoppers, voles and bison, followed by the secondary consumers, shrews, hawks and small cats.
Primary production provides for all trophic members as it provides energy to primary consumers that in turn provide energy to secondary consumers and so forth.
