Question

What is photosynthesis​

Answer 1

It is the process plants use to make food.

Answer 2

Answer:

photosynthesis is the process in which plants and some protists get their energy.  They start by taking in sunlight and CO2.  After taking out the needed nutrients, they will release O2.  This is also how all humans haven't died to suffocation.  The CO2 we breath out is converted to O2 by plants.  Hope this helps you out.
