Document Summary

Morphological/typological species concept: traditional concept species is a different thing, looks different or is of a different kind species=real simplest concept=practical, operated on ideas about evolution. ( pre darwinian classification scheme) Decomposers producers cyanobacteria, algae, plants produce complex organic molecules through light chemotrophs metabolize inorganic chemicals to generate energy fungi and bacteria obtain energy by breaking down complex organic matter into simple + inorganic saprophytes= consume dead org parasitic decomposers= don"t wait for organism to die consumers animals cant obtain energy directly from inorganic chemical source or light so they consume primary producers herbivores feed directly on producers carnivores feed on herbivores omnivores feed on all types. Mixotrophs use inorg chemicals as energy source e donors and co2 as carbon source use org chemicals as energy sources e donors as carbon source (these are heterotrophs) use inorg chemicals as e donors organic chemicals as carbon source.
