Question

Which path through the carbon cycle is possible?

Answer 1

Answer:

Plant to animal to atmosphere.

Explanation:

• The carbon cycle describes the recycling of carbon from and back to the atmosphere.
• Plants utilize the carbondioxide present in the atmosphere to produce carbohydrates in the presence of light through the process of photosynthesis.
• When plants are consumed by animals, the carbon becomes a part of the animal.
• Animals break down glucose molecules into energy (ATP), releasing water and carbondioxide in a process called cellular respiration.
• This carbondioxide, as it is useless for animal cells, is released back into the atmosphere through gaseous exchange in the lungs.
