The correct response is:
The carbon in carbon dioxide is recycled during photosynthesis.
During photosynthesis, plants take in carbon dioxide from the atmosphere and use it, along with water and sunlight, to produce glucose and oxygen. The carbon from carbon dioxide is thus incorporated into organic compounds produced by the plant.
The correct response is:
The hydrogen in glucose is recycled when water is formed.
During cellular respiration, glucose is broken down, and hydrogen atoms from glucose combine with oxygen to form water, thereby recycling hydrogen in the process.
The correct response is:
It was recycled when glucose was formed.
During photosynthesis, the radioactive hydrogen from the water is incorporated into glucose as the plant synthesizes carbohydrates.
