They Say It's Important Cause it Gives Energy and light .
Photo-Synthesis is important to a plant's life. It produces food for it through this process. Without this process plants will not be there and hence we will be not here.
grade 9 academic science ?? ;) anyhow... photosythesis should win the most important chemical reaction on earth "award" because if there was no photosynthesis, it would mean the end of plants generating oxygen. So therefore all living things would die because no living things can survive without oxygen!
Drangonflies are important to life on earth because they eat the mosquitoes which no one likes.
Without the atmosphere, there would be no life on earth.
Our life is indirectly dependent on photosynthesis because we depend on plants for food. Plants make food by photosynthesis.
