Question

difference between photosynthesis, respiration and digestion

Answer 1

hey friend here is ur answer

One difference of photosynthesis andrespiration is that their process is being reversed. In photosynthesis, carbon dioxide and water is yielded to glucose or also known as sugar and oxygen while in respiration, it is the other way around. Sugar and oxygen is yielded to carbon dioxide and water.The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. In this system, the process of digestion has many stages, the first of which starts in the mouth.

Answer 2

Photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

Respiration
a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

Digestion
sequence by which food is broken down and chemically converted so that it can be absorbed by the cells of an organism and used to maintain vital bodily functions.breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma
