Examplesofautotrophautotroph Based on our basic biological assumption regarding autotrophs, we believe there must exist metabolic pathways for generating these metabolites. From theCambridge English Corpus Possessing changes in microorganism type is obvious for multi-species biofilms that have distinctly different microbial types, such as heterotrophs and autotrophs. From theCambridge English Corpus For a particular model population, nullclines connect combinations of grazer andautotrophbiomass values where growth of the population is zero. From theCambridge English Corpus The general picture one should take away from this brief review is one of great stoichiometric variability and plasticity at the base ofautotroph-driven food webs. From theCambridge English Corpus Thus, in a world with stoichiometric reality, an ecosystem can be maintained indefinitely in a state of highautotrophbiomass and no (or low) herbivore abundance. From theCambridge English Corpus 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 theautotroph. From theCambridge English Corpus Stoichiometric theory provides an alternative or perhaps a complementary mechanism to explain the very long persistence of anautotroph(stromatogenic cyanobacteria)dominated world. From theCambridge English Corpus Trophic mutualism often occurs between anautotrophand a heterotroph.
