question 15
choose the statement that correctly explains how carbon is cycled.
plants release carbon as sugars; animals consume plants and convert the sugars to carbon dioxide again.
animals use carbon that is released by plants, which are converted to sugars when ingested and back to carbon dioxide when exhaled.
plants pull carbon dioxide from the air and grow; animals eat plants and grow, releasing carbon dioxide back into the air.
animals eat plants and create carbon dioxide; plants release carbon and use water and sunlight to grow.

Explanation:

Plants perform photosynthesis, taking in carbon - dioxide from the air to grow. Animals consume plants and through respiration, release carbon - dioxide back into the air, which is a key part of the carbon cycle.

Answer:

Plants pull carbon dioxide from the air and grow; animals eat plants and grow, releasing carbon dioxide back into the air.
