Question

an active carbon cycle is critical for a functioning biosphere. several key processes within the carbon cycle involve the movement of carbon into, from, or within the biosphere.

• plants use carbon dioxide gas (co₂) from the atmosphere during photosynthesis to make carbon - based molecules, such as carbohydrates.
• when animals consume plants or other animals, the carbon - based molecules they eat are broken down and used for energy and making new carbon - based molecules.
• during cellular respiration, plants and animals release carbon dioxide back into the atmosphere.
• fungi and bacteria break down carbon - based molecules in dead organisms during decomposition. this releases carbon back into the atmosphere and geosphere.

select the true statements.
carbon from living and dead organisms can be transferred to the atmosphere.
only animals release carbon into the atmosphere during cellular respiration.
plants use carbon from the atmosphere during photosynthesis.
carbon moves from the biosphere to the atmosphere and geosphere during decomposition.

Explanation:

• The text states that during cellular respiration, both plants and animals release carbon - dioxide back into the atmosphere, so the statement "Only animals release carbon into the atmosphere during cellular respiration" is false.
• It is mentioned that plants use carbon dioxide from the atmosphere during photosynthesis, carbon from living and dead organisms can be transferred to the atmosphere (through respiration and decomposition), and during decomposition, carbon moves from the biosphere to the atmosphere and geosphere.

Answer:

• Carbon from living and dead organisms can be transferred to the atmosphere.
• Plants use carbon from the atmosphere during photosynthesis.
• Carbon moves from the biosphere to the atmosphere and geosphere during decomposition.
