Explanation:Photosynthesis is the process by which green plants produce their own food.Carbon dioxide from the atmosphere is taken in by leaves through stomata and used to make carbohydrates, primarily glucose and starch, during this process.When the glucose is in excess it is stored in the form of starch. It is stored in the roots, leaves, tubers, and bulbs.During the process, oxygen is released.The presence of starch (glucose) in leaves indicates the occurrence of photosynthesis. Starch is also a carbohydrate.It is a unique process on the earth. The solar energy is captured by the leaves and stored in the plant in the form of food.Photosynthesis occurs only in the green parts of plants, primarily the leaves.Additional InformationRespiration:Respiration is defined as a metabolic process in which an organism's living cells obtain energy by taking in oxygen and emitting carbon dioxide as a result of the oxidation of complex organic substances.Degradation:Degradation is a process in which the value of the biophysical environment is affected by a variety of human-caused processes that act on the land.Mineral absorption:Mineral absorption, also known as mineral uptake, is the process by which minerals enter cellular material.
