Why photosynthesis is important?

The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet’s living systems are powered by this process. It’s not particularly efficient by human engineering standards, but it does the job.

Why is photosynthesis important to humans?
Humans depend on photosynthesis to make the food they consume, as a source of energy to produce heat, light, and electricity, on a daily basis.
