Question

1. Why is life on Earth not possible without plants? Explain using elements/ CO2 O2 and H2O

Answer 1

Life on Earth would not be possible without plants. Plants take in CO2 (carbon dioxide) and give out O2 (oxygen). Plants also need H2O (water) to keep them alive which they use in a process called photosynthesis. O2 is what all living beings need to survive on this planet. That and H2O.

Hopefully, this helps.

Answer 2

Every living thing needs it even us. It keeps us alive because we need it or we will die
