Question

how can the carbon in animal wastes reach the atmosphere?
photosynthesis, organic carbon, underground storage
decomposition, fossil fuel formation, fossil fuel emissions
fossil fuel emissions, diffusion, ocean storage
transpiration, diffusion, ocean storage
question 2(multiple choice worth 3 points)
(04.05 mc)
which statement best describes the role of animals in the water and carbon cycles?
animals release carbon dioxide and water vapor as a by - product of cellular respiration.
animals release carbon dioxide and water vapor as a by - product of photosynthesis.
animals take in carbon dioxide and oxygen during cellular respiration.
animals use oxygen to perform photosynthesis and release carbon dioxide as a by - product.

Explanation:

For the first question, animal wastes decompose. Over long - time periods, the carbon in them can be involved in fossil fuel formation and then released to the atmosphere through fossil fuel emissions. For the second question, animals perform cellular respiration where they take in oxygen and release carbon dioxide and water vapor as by - products.

Answer:

1. Decomposition, fossil fuel formation, fossil fuel emissions
2. Animals release carbon dioxide and water vapor as a by - product of cellular respiration.
