In what form is carbon found in the atmosphere? a - co2 b- c6h12o6 c- h2o d - atp

Hello.

The answer here is “”, since  means “Carbon Dioxide” (hence the prefix
‘Di’, meaning two), and is composed of two oxygen atoms and one carbon atom. An example of this to support the answer is the connection between humans and trees. Trees take in carbon and release oxygen, being put forth into the air. While this occurs, humans (or any land life, generally) take in the oxygen that is exerted by the trees and then release carbon, which trees intake, ultimately creating a never-ending cycle.
 is referred to as “Glucose” - 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen molecules (I call it a sandwich to remember).
“” is a element known as water. This element is composed of two hydrogen molecules and one oxygen molecule.
“ATP” (or ‘Adenosine Triphosphate’) is a small molecule that is used in cells.

I hope this helps!
