Learn about examples of autotrophs and heterotrophs. Discover what the energy autotrophs use to make food is, and examine why decomposers are...
Referred to as heterotrophs, they rely on the autotrophs directly, i.e. by eating them, or indirectly, i.e. by eating organisms that feed on autotrophs. The starch stored by photoautotrophs is an energy-rich carbohydrate and therefore it is a vital source of energy for various ...
Types of Autotrophs As there are many types of heterotrophs, there are different types of autotrophs. Remember, autotrophs make their own energy, they can also be labeled as producers. Photosynthesis, the process of turning light and water and carbon dioxide into glucose, is the most common...
AutotrophsWhat is the difference between autotrophs and heterotrophs? In essence, autotrophs are organisms capable of making nutritive organic molecules from inorganic materials. Thus, they differ from heterotrophs in having the capability of producing their own food and need not consume other ...
In terms of carbon utilization, there are autotrophs and heterotrophs, and in terms of energy consumption, there are chemoorganotrophs, chemolithotrophs, and phototrophs. Aerobic bacteria use oxygen as an electron acceptor; anaerobic bacteria use alternate electron acceptors such as nitrate, ferric...
Organisms acquire energy in a food chain through three primary sources: from inorganic sources, from organic matter, and from decomposing dead organic material or wastes. Producers, also known as autotrophs, directly obtain food from inorganic sources, while consumers, or heterotrophs, acquire food ...
Cyanobacteria is a photosynthetic autotroph believed to be Earth’sfirst oxygen producer. Also called blue-green algae or pond slime, cyanobacteria are present in nearly all types of water, including freshwater, saltwater and brackish water. It is the only bacteria capable of producing oxygen during...

Metabolically, Deltaproteobacteria can be divided into three major categories namely,chemoorganotrophs/chemoorganoheterotroph, chemolithoheterotrophs, and chemolithoautotrophs. Moreover, as mentioned, they can be divided based on whether they use oxygen for respiration or not and whether they are capable...
Chemoautotrophs and Chemoheterotrophs Chemoautotrophs obtain their energy from chemical reactions and synthesize organic compounds from carbon dioxide. The energy source for chemosynthesis may be elemental sulfur, hydrogen sulfide, molecular hydrogen, ammonia, manganese, or iron. Examples of chemoautotroph...
