In most living things, respiration requires oxygen. Determine the relationship between this type of respiration and photosynthesis.

Respiration and photosynthesis are two fundamental processes in most living organisms that are closely related.

1. Respiration: This is a process where oxygen is used to break down glucose (or other organic molecules) to produce energy in the form of ATP (adenosine triphosphate). This process also produces carbon dioxide and water as by-products. This process occurs in the mitochondria of cells.

2. Photosynthesis: This is a process that occurs in plants, algae, and some bacteria. They use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process occurs in the chloroplasts of cells.

The relationship between these two processes is that the products of one are the reactants of the other.

• The oxygen produced in photosynthesis is used in respiration to break down glucose and produce energy.
• The carbon dioxide produced in respiration is used in photosynthesis to produce glucose.

In this way, these two processes form a cycle, balancing the levels of oxygen and carbon dioxide in the atmosphere. This balance is crucial for the survival of most life forms on Earth.
