Question

Carbon in food molecules is transferred from animals to the geosphere through the process of

diffusion
excretion
photosynthesis
respiration

Answer 1

The right option is; respiration

Carbon in food molecules is transferred from animals to the geosphere through the process of respiration.

Respiration is a biochemical process in living organisms which involve the production of chemical energy, mainly with the intake of oxygen and the release of carbon dioxide, water, and ATP (Adenosine triphosphate) from the oxidation of complex organic substances such as carbohydrates. The two different types of respiration are; cellular respiration and physiological respiration.

Answer 2

Answer: Excretion.

Step-by-step explanation:

The food that animals intake is digested inside the body for the production of energy. The food is broken down into smaller particles and absorbed in the small intestine.

The undigested food matter in a solid form is excreted out of the body in the form of feces that contains carbon in it. This is how the food(carbon) is moved out of the body of animals and reaches the geosphere.
