Producers Summary
288 words, approx. 1 pages Producers, sometimes called primary producers, are organisms that make their own food. Because these organisms change relatively simple inorganic nutrients into more complex, energy-rich, organic forms, they are autotrophs. Thus, they do not need any...

Autotroph Summary
258 words, approx. 1 pages Autotrophs are organisms that are capable of making their own food. They are "self feeders." These organisms make their own food by converting relatively simple inorganic nutrients into more complex, energy-rich, organic forms. Thus, the autotrophs do...

Autotrophic Bacteria Summary
222 words, approx. 1 pages An autotroph is an organism able to make its own food. Autotrophic organisms take inorganic substances into their bodies and transform them into organic nourishment. Autotrophs are essential to all life because they are the primary producers at the...

Autotroph Information
340 words, approx. 1 pages
 An autotroph (from the Greek autos = self and trophe = nutrition) is an organism that produces complex organic compounds from simple inorganic molecules and an external source of energy, such as light or chemical reactions of inorganic compounds....

Consumer species richness and autotrophic biomass.
12/01/1998: 7,513 words, approx. 25 pages We tested whether standing autotrophic (unicellular algal) biomass is sensitive to variation in initial consumer (nondecomposer, heterotrophic protistan) diversity in experimental microbial microcosms. Our results showed a strong, negative relationship between autotrophic biomass and consumer species richness. Additional microcosm experiments showed that this relationship...

A New Role for Autotrophic Methanogens?
03/01/2005: 1,657 words, approx. 6 pages For many years, wastewater engineers have known that the microbial communities in anaerobic digesters include autotrophic methanogens. These organisms live on the energy from the reaction CO2 + 4H^sub 2^ [arrow right ] CH^sub 4^ + 2H^sub 2^O, obtaining the carbon dioxide and hydrogen...
