Trees take in _____and give out oxygen to nature.
Hint:
During process of photosynthesis trees take in Carbon dioxide and give out oxygen.
The correct answer is: Carbon dioxide
Trees take in carbon dioxide and give out oxygen to nature, which is used by us for survival. Cutting down trees for land availability due to a rise in population to bring up new industries has created an imbalance in the ecological system, resulting in a decrease in the oxygen levels in the air.
