• A. Both $A$ and $A$
• B. Producers
• C. Consumers
• D. None of the above

Answer 1

The correct option is A Both $A$ and $A$

Producers
Plants are called producers because they fix carbon dioxide. Producers perform photosynthesis to fix atmospheric carbon dioxide into glucose molecules.

Consumers
Consumers are organisms which depend on other organisms for their food. Examples include lion, tiger etc.

Respiration
Respiration is the production of energy rich molecules like ATP, carbon dioxide and water from glucose molecules in food using oxygen. Respiration is done by both producers and consumers. Hence a considerable amount of carbon returns to the atmosphere as $C{O}_2$ through respiratory activities of the producers and consumers.

Final answer
(C) Both A and B
