All living organisms exist due to solar energy, contained in organic compounds formed in the process?

This is the process of photosynthesis. It is characteristic of green plants and some representatives of the kingdom of bacteria, protists and animals. The essence of photosynthesis is that special organelles (chloroplasts) use inorganic substances and, under the influence of sunlight, synthesize glucose. Also, oxygen is released during the reaction. It is a by-product of the reaction. Heterotrophs cannot make glucose on their own. Therefore, they eat plants or other heterotrophs to get the right amount of organic matter.
