Organisms that use CO 2 as their source of carbon are called

Okay, everyone. Organisms that use Carbon Dioxide as their source of carbon are called what? Okay. So we categorize organisms by where they get their energy from, where they get their carbon sources from, and where they get their electron sources from. So c02 is one of the very major carbon sources for certain types of organisms. CO2 or carbon dioxide is an inorganic molecule. So that means that it is not an organotroph, because organotrophs get their energy from organic molecules, and c02 is an inorganic molecule, so that's not correct. Heterotroph is not going to be correct either because heterotrophs are organisms that get their carbon from organic molecules. These are organisms that cannot generate their own organic molecules or their own carbon sources, so they have to consume organic molecules from other organisms to get their carbon. They cannot make their own carbon sources, so that's not what we're looking for. Autotrophs, however, are able to make their own carbon sources from inorganic carbon molecules, specifically CO2. A major example of an autotroph is a plant, which takes in c02 and builds glucose molecules with that carbon. So the correct answer here is probably gonna be autotrophs because they commonly get their carbon sources from inorganic molecules like carbon dioxide. Chemotroph isn't gonna be what we're looking for because a chemotroph is telling us where this organism is getting its energy. They're just telling us that it's getting getting its energy from chemicals. But we're asking about a carbon source, not an energy source. So we're not looking for chemotrophs. The correct answer here is answer choice c. An autotroph is an organism that can get its sources of carbon from carbon dioxide. A really great example of this is a plant. Okay, everyone. Let's move on to our next video.

Verified step by step guidance

Begin by understanding the definitions of each term provided in the options. This will help in identifying the correct classification of organisms based on their carbon source.

Organotrophs are organisms that obtain electrons from organic compounds. They are not defined by their carbon source, but rather by their electron source.

Heterotrophs are organisms that obtain their carbon from organic compounds, not CO2. They rely on consuming other organisms or organic matter for their carbon needs.

Autotrophs are organisms that use CO2 as their carbon source. They are capable of fixing carbon dioxide to synthesize organic compounds, making them self-sufficient in terms of carbon acquisition.

Chemotrophs are organisms that obtain energy from chemical compounds. This term describes their energy source rather than their carbon source.
