Question

Look carefully at the model. Plants take in and release carbon dioxide. Plants take in carbon dioxide for photosynthesis. What process releases carbon dioxide back into the atmosphere?

Answer 1

It is called the carbon cycle

Answer 2

Answer:

The correct answer would be cellular respiration.

Cellular respiration refers to the set of biochemical reactions take place in an organism which helps in the production of energy in the form of ATP (adenosine triphosphate).

It harnesses the chemical energy present in the food (glucose mainly) and converts it into the energy currency of the cell, that is, ATP.

Carbohydrate and oxygen are the substrate of cellular respiration and carbon dioxide, water, and energy (ATP) are the products.

C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP
