What does organism use carbon dixode and Nitrogen for?

Answer 1

Plants and other autotrophs use carbon dioxide to make food: carbon dioxide is the source of carbon which makes glucose in photosynthesis.

Nitrogen is vital for all life. Proteins and nucleic acids (such as DNA), which perform the majority of the functions of living organisms, are made up of some nitrogen. Nitrogen thus is needed to make proteins and nucleic acids.

Answer 2

Plants and other autotrophs (organisms that can make food from sunlight) use carbon dioxide in photosynthesis, more specifically, in the dark reaction to produce glucose which is food.

Animals, or rather mammals, use carbon dioxide in the form of hydrogencarbonate/bicarbonate in their blood. This helps to regulate the pH of the blood.

Nitrogen is an element found in all organisms in proteins and nucleic acids, where proteins perform many functions in the body, and nucleic acids, e.g. DNA, carry the organism's genetic information.
