Final answer:
Photosynthesis and cellular respiration are related to the oxygen cycle as they involve the production and utilization of oxygen.
Step-by-step explanation:
Photosynthesis and cellular respiration are both processes involved in the oxygen cycle. In photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose and release oxygen as a byproduct. This oxygen is then utilized by organisms during cellular respiration where glucose and oxygen are converted into carbon dioxide, water, and energy. This continuous exchange of oxygen between photosynthesis and cellular respiration is crucial for maintaining the oxygen cycle on Earth.
