Question:they depend on energy stored in chemical bonds by autotrophs for their food energy? I am making sure ! I need an A on my test!thanks! thanks!!!!

Answers:You are correct.

Question:Don't worry this is not a question so I can copy your answer to answer from the text book. I'm just confused on the difference. What one uses photosynthesis ? Aren't they the same thing?

Answers:Producer: provides food for others. And example would be a cow is the producer and man would be a consumer. The cow provides food to man. Autotroph: provides food for self..hence photosynthesis. Plants do photosynthesis which is energy from the sun, plant creates its own sugars for food.

Question:what is the difference between an autotroph and a heterotrph? Describr the source or energy each relies upon.

Answers: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. Autotrophs are considered producers in a food chain. Plants and other organisms that carry out photosynthesis are phototrophs (or photoautotrophs). Bacteria that utilize the oxidation of inorganic compounds such as hydrogen sulfide, ammonium or ferrous iron as an energy source are chemoautotrophs (some are known as lithotrophs). Autotrophs are a vital part of the food chains of all ecosystems. They take energy from the environment (sunlight or inorganic sources) and use it to process carbon-based and other organic molecules that are used to carry out various biological functions such as cell growth. Other organisms, called heterotrophs, utilize autotrophs as food to carry out these same functions. Thus, heterotrophs animals, fungi, as well as most bacteria and protozoa depend on autotrophs for both energy and raw materials to make complex organic molecules. This mechanism is called primary production in the sea. Heterotrophs obtain energy by breaking down organic molecules obtained in food. Carnivorous animals ultimately rely on autotrophs because the energy and organic building blocks obtained from their prey comes from autotrophs they preyed upon. There are some species of organisms that require organic compounds as a source of carbon, but are able to use light or inorganic compounds as a source of energy. Such organisms are not defined as autotrophic, but rather as heterotrophic. An organism that obtains carbon from organic compounds but obtains energy from light is called a photoheterotroph, while an organism that obtains carbon from organic compounds but obtains energy from the oxidation of inorganic compounds is termed a chemoheterotroph. A heterotroph (Greek heterone = (an)other and trophe = nutrition) is an organism that requires organic substrates to get its carbon for growth and development. A heterotroph is known as a consumer in the food chain. Contrast with autotrophs which use inorganic carbon dioxide or bicarbonate as sole carbon source. All animals are heterotrophic, as well as fungi and many bacteria. Some parasitic plants have also turned fully or partially heterotrophic, whereas carnivorous plants use their flesh diet to augment their nitrogen supply, but are still autotrophic. Heterotrophs are unable to synthesize organic, carbon based compounds independently from the inorganic environment's sources (e.g. Animalia, unlike Plantae, cannot photosynthesize) and therefore must obtain their nutrition from another heterotroph or an autotroph. For a species to be termed a heterotroph, it must obtain its carbon from organic compounds. If it obtains nitrogen from organic compounds, but not energy, it will be deemed an autotroph. If a species obtains carbon from organic compounds then there are two possible subtypes of these heterotrophs: * photoheterotroph obtains energy from light and must obtain carbon in an organic form * chemoheterotroph obtains energy from the the consumption of organic molecules and an organic form of carbon In simpler terminology, a heterotroph is an organism that is incapable of making its own food from light or inorganic compounds, and feeds on organisms or the remains of other organisms to get its necessary energy to survive.

The Heterotrophic Blues

"Heterotroph Shmeterotroph" declares the Crenshaw High School student to his father, "I'm not going to learn this stuff anyway. Might as well kick it and watch MTV". Thus starts this zany little music video in which a kid finds he can learn all about "the heterotroph hypothesis" by watching "Elvis Parsley" sing a rockabilly lesson about how tough it is for those of us who depend on autotrophs for our daily bread. The video, made in 1990, features TH and his kids from the 'hood playing horns while Dr. Sherry Kerr's students from Beverly Vista Middle School in Beverly Hills play vegetables. Shot at Beverly Hills Television, this was a pioneering attempt to bring kids from the poor areas of LA together on a project with wealthy kids from Beverly Hills, and it occurred during a time of economic depression in LA that preceeded the LA riots. Because of our Melodic-Mnemonics program we were able to bring the communities together during the time of the worst violence and intolerance that followed.

Science & Chemistry Facts : What Are Some Examples of Heterotrophs?

Some examples of heterotrophs are all animals, all fungi and many bacteria. Any organism that has to get energy from consuming other organic beings is considered a heterotroph.
