The majority of the lichens contain eukaryotic autotrophs belonging to the Chlorophyta ( green algae ) or to the Xanthophyta ( yellow-green algae ).

Those creatures that can take in energy in its pure form, i . e ., electromagnetic radiation, are termed " autotrophs ."
43.
The sugars and other molecular components produced by the autotrophs are then broken down, releasing stored solar energy, and giving the heterotroph the energy required for survival.
44.
The base or basal species in a food web are those species without prey and can include autotrophs or top consumer, which is usually a larger predatory carnivore.
45.
Therefore, primary consumers get about 10 % of the energy produced by autotrophs, while secondary consumers get 1 % and tertiary consumers get 0.1 %.
46.
:: Following the link in Consumer to the biological form of the word, I get Heterotroph, which links to Autotroph, the scientific word for producers.
47.
Autotrophs produce usable energy ( in the form of organic compounds ) using light from the sun or inorganic compounds while heterotrophs take in organic compounds from the environment.
48.
*"'Digestive symbyotes "' Digestive symbyotes are an example of an important trophic mutualism that does not occur between an autotroph and heterotroph.
49.
Excessive phosphorus can make for excessive production of autotrophs, like algae and cyanobacteria, leading to "'eutrophication "'in an inorganic nutrient pathway.
50.
When autotrophs are eaten by heterotrophs, i . e ., consumers such as animals, the carbohydrates, fats, and proteins contained in them become energy sources for the heterotrophs.
