Exempel på autotroph

• Based on our basic biological assumption regarding autotrophs, we believe there must exist metabolic pathways for generating these metabolites.

• 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.

• 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.

• Being an autotroph it receives energy from growing on sulfur or even a variety of organic compounds.

• Unlike some of its relatives, this species is an autotroph.

• From this carbon-based hypothesis the scientific team assumed some form of staple photosynthesizing animal/plant combination would be the principal autotroph.

• Some endoliths have specialized in feeding on their autotroph relatives.
