Answer 1

MARK IT AS A BRAINLIST ANSWER ..

Explanation:

Trees create an ecosystem to provide habitat and food for birds and other animals. Trees absorb carbon dioxide and potentially harmful gasses, such as sulfur dioxide, carbon monoxide, from the air and release oxygen. One large tree can supply a day's supply of oxygen for four people

Answer 2

Answer:

The carbondioxide given out by the factories, vehicles, humans and animals is taken by the trees. Carbondioxide is a very essential aspect of making their food and glucose (C6 H12 O6). Thus to fulfill our requirment they give oxygen+ glucose. And that oxygen is bot less it give O6 oxygen.

A one metre tree gives out more than 500 g of oxygen in a day.

The Amazon Forest, which is at fire at present gives out more than 20% of the Earth's oxygen.

That's why we should plant trees in our society. This helps in living of Humans and animals.
