NEET BIOLOGY

Detailed explanation-1: -According to the Arbor Day Foundation, in one year a mature tree will absorb more than 48 pounds of carbon dioxide from the atmosphere and release oxygen in exchange. So next time you take a deep breath of air give credit to a tree or hug a tree in thanks for what it gives us – the very air we breathe.

Detailed explanation-2: -To eat, trees go through a process called photosynthesis. To do this, their leaves pull in carbon dioxide and water through tiny pores, called stomata, and use energy absorbed from the sun to turn the CO2 and H2O into sugars. During that process, the tree releases 02, which is oxygen, from the leaves’ stomata.

Detailed explanation-3: -Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.

Detailed explanation-4: -Trees do most of the work creating oxygen and cleaning the air of gases like carbon dioxide in the spring and summer. For the most part, they take a kind of fall and winter vacation. Still, at any given moment there is a tree on our planet creating the oxygen that we breathe.

Detailed explanation-5: -We need at least 1 mature trees or 4 to 5 small trees to make enough oxygen for 1 person. The bigger and older the tree is, the more oxygen we will get.
