Question

Why don't birds suffocate due to carbon dioxide near trees when they sleep at night?

Answer 1

Because, although the trees emit carbon dioxide during the night as part of their respiration function, the percentage of the carbon dioxide in the air never reaches a dangerous level, or even discomfort level. Let's not forget that the trees are in open air with sufficient oxygen always present, not in greenhouses or closed rooms!!!.

Answer 2

trees convert carbon dioxide to oxygen..... air around a tree is therefore rich in oxygen.....
