What uses organic molecules for both nutrition and energy?
An autotroph or primary producer is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis).
Which category of organisms depends on organic molecules as the source of both energy and carbon?
AP Chapter 27 – Prokaryotes (detailed)
| A | B |
|---|---|
| An organism that needs only carbon dioxide as a carbon source but obtains energy by oxidizing inorganic substances is called a(n) _____. | chemoautotroph |
| An organism that must consume organic molecules for both energy and carbon is called a(n) _____. | chemoheterotroph |
What organisms are Chemoheterotrophs?
Chemoheterotrophs are the most abundant type of chemotrophic organisms and include most bacteria, fungi and protozoa.
Which organism relies upon organic compounds for its carbon and energy needs quizlet?
Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur. Which organism relies upon organic compounds for its carbon and energy needs? Heterotroph.
How does an animal take in organic molecules?
Animals combine oxygen chemically with hydrogen atoms that they remove from their food—that is, from organic materials such as sugar, protein, and amino acids. Animals release water as a waste product from the oxygen respiration. Animals, like all heterotrophs, use organic materials as their sole source of carbon.
Are organisms that depend on an external source of organic compounds?
heterotroph, in ecology, an organism that consumes other organisms in a food chain. In contrast to autotrophs, heterotrophs are unable to produce organic substances from inorganic ones. They must rely on an organic source of carbon that has originated as part of another living organism.
What is the name given to organisms that use chemicals as their energy source?
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.
Which microorganism uses inorganic chemicals for energy and carbon dioxide for carbon?
Chemoautotrophs
Chemoautotrophs: microbes that oxidize inorganic chemical substances as sources of energy and carbon dioxide as the main source of carbon. 2. Chemoheterotrophs: microbes that use organic chemical substances as sources of energy and organic compounds as the main source of carbon.
