The diagram below represents a process that occurs in human systems. This process is known as 1 excretion respiration circulation 3 A digestion

The process described by the chemical equation in the picture details involves the conversion of a complex sugar into two simple sugars with the help of a catalyst, and the production of water as a byproduct. This process is characteristic of digestion, where complex carbohydrates (complex sugars) are broken down into simpler sugars that can be absorbed by the body.Let's analyze the options given:1. Excretion: This is the process of removing waste from the body. The chemical equation does not describe waste removal.2. Respiration: This is the process of breathing and using oxygen to produce energy from food substances. The equation does not describe this process.3. Circulation: This refers to the movement of blood and other substances around the body. The equation does not describe the movement of substances.4. Digestion: This is the process by which food is broken down into smaller, absorbable components. The equation describes the breakdown of a complex sugar into simple sugars, which is a part of digestion.Step by step, we have identified that the process described by the chemical equation is digestion.Answer: 4. Digestion
