Answer 2

They don’t need oxygen and also don’t need only at night, they need carbon dioxide and also need it during day, like we can’t survive without oxygen so same situation are for them
We all say not to cut tree but what will happen if we cut more and more tree let me explain:-
As we all know our world population is going up with a very high speed so if we cut trees then trees will be too much fewer than humans
As they release oxygen which are waste for them but it is too much precious for humans but the trees are too much few than the number of humans hence we don’t have enough oxygen for us to breathe
And the carbon dioxide that we release as waste they are also too precious for plants but if there are a few number of plants as compare to humans so what will happen from the remaining carbon dioxide?? Nothing , they will mix up air, as a result the percentage of oxygen will go down and the percentage of carbon dioxide will go higher
In some years It can also be very difficult to breathe if situations will go on like this
