Question

How are photosynthesis and respiration related to each other?

Answer 1

Hint: The end result of Photosynthesis is glucose that is further used in cellular respiration to make ATP. The glucose is then converted into carbon dioxide, which is used in the process of photosynthesis. While water is broken down to make oxygen during the process of photosynthesis, in the process of cellular respiration oxygen is mixed with hydrogen to form water.
The relationship between the two photosynthesis and cellular respiration is such that the end results of one system are the reactants of the other process.

Complete answer:
Humans, animals as well as plants depend on the cycle of cellular respiration along with the process of photosynthesis for their survival. The oxygen produced by green plants during the process of photosynthesis is what humans as well as animals inhale for the blood to transport to the cells for the process of respiration.
The carbon dioxide produced during respiration is liberated from the body and absorbed by green plants to help provide the energy they need for growth along with their development. This is the never ending cycle that sustains life on this planet. The cycle of photosynthesis as well as respiration maintains the balance of oxygen and carbon dioxide.
Photosynthesis consists of the use of energy from sunlight, water as well as carbon dioxide to produce glucose and oxygen. Cellular respiration in humans uses glucose and oxygen to create carbon dioxide and water.

Note: Photosynthesis along with cellular respiration are both key components of a mutually beneficial relationship. Cellular respiration cannot operate without photosynthesis, as well as photosynthesis certainly cannot process without the help of its partner.
