Monerans are classified into two phyla, or groups, autotrophs, and heterotrophs. Autotrophs are able to create their own food, similar to plants. Heterotrophs can not create their own food, and so must rely on autotrophs as their food source.
Monerans play various roles in almost all food chains, including producer,consumer, and decomposer.
Cyanobacteria are important oxygen producers.
monerans Members of the kingdom Monera, which consists of prokaryotic organisms.
monestrous A species in which the female is receptive for only a few days once each year.
A photosynthetic protist or moneran will go toward light while a flatworm or other organism such as a "mealy bug" will move away since light usually means heat and drying out.
