Carbon dioxide

Oxygen

Plants and other producers use carbon dioxide in photosynthesis.

They produce oxygen as a waste product. Carbon dioxide moves

from the air into the leaves of plants. Oxygen moves from the

plant into the air through the leaves.

Almost all living things, including plants, get energy from cellular

respiration. This process releases energy from the sugar molecules

in food. Oxygen is used in cellular respiration. Carbon dioxide is

produced as a waste product.

The oxygen produced during photosynthesis is used in cellular

respiration. The carbon dioxide produced in cellular respiration is

used in photosynthesis. This is the oxygen-carbon dioxide cycle.
