Question

If the trees release co2 at night, so how humans get oxygen at night? From what source?

Answer 1

hey friend here is ur answer_________
Trees can't take credit for all the oxygen in the world. In fact, algae and other marine plants produce an estimated 70 percent of Earth's oxygen through the photosynthesis process that takes place in oceans. Yes trees are important because even a slight drop in the oxygen percentage in atmosphere can wreck havoc, but i guess it answers your question, oceans provides the earth with most of the oxygen. That is the reason why our climate scientists are so concerned about the increasing pollution of our oceans, because if living creatures of the oceans die due to man made pollution , then Humanity RIP! so we should hav to conserve it soon.
