Photosynthesis is one of the most important processes in our planet's ecosystem. Every living thing needs the energy to survive, and this process provides that for every plant on earth! Photosynthesis is a process that splits water molecules and uses the energy from the Sun to convert them back into oxygen and hydrogen. This process is necessary for life on Earth, as it produces the oxygen we need to breathe. It’s amazing how much we can and still want to know and learn about this amazing world that we live in.
