Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
Furthermore, what is the biological importance of photosynthesis for the ecosystem?
Photosynthesis is very important for our biosphere. Photosynthetic plants convert solar energy into the chemical energy and that stored chemical energy flows into herbivores, predators, parasites, decomposers, and all other forms of life .
One may also ask, why is photosynthesis important to humans?
Photosynthesis is important, in fact essential, to all life for a number of reasons. Because of photosynthesis, plants essentially function as filters that take carbon dioxide, which is poisonous to humans and many other life forms, from the atmosphere and replace it with oxygen, which makes life possible.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize food from carbon dioxide and water. Green plants absorb carbon dioxide from air and water from the soil. In the presence of sunlight and chlorophyll they synthesize starch as food.
