Possessing changes in microorganism type is obvious for multi-species biofilms that have distinctly different microbial types, such as heterotrophs and autotrophs. For a particular model population, nullclines connect combinations of grazer and autotroph biomass values where growth of the population is zero. The general picture one should take away from this brief review is one of great stoichiometric variability and plasticity at the base of autotroph-driven food webs. Thus, in a world with stoichiometric reality, an ecosystem can be maintained indefinitely in a state of high autotroph biomass and no (or low) herbivore abundance. However, net fixation is probably substantially lower than gross fixation because in strict autotrophs a certain percentage of photosynthate must be used to meet the metabolic needs of the autotroph. Stoichiometric theory provides an alternative or perhaps a complementary mechanism to explain the very long persistence of an autotroph (stromatogenic cyanobacteria)dominated world. Trophic mutualism often occurs between an autotroph and a heterotroph. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These reduced carbon compounds can be used as an energy source by the autotroph and provide the energy in food consumed by heterotrophs.

Each food chain starts with a primary producer or autotroph, an organism, such as a plant, which is able to manufacture its own food.

As an estimate of autotroph biomass, it is only a rough indicator of primary production potential, and not an actual estimate of it.
