Trees give oxygen and paper. They are also used for buildings. Last of all, trees are a habitat for some animals and can even provide apples , leaves and etc.
On average an adult would need about 200 trees in a air tight room for one hour to last an adult a a day while a baby only needs 67.
The physical features that make up the UNITED STATES are: 1. THE MOUNTAINS 2. THE RIVERS 3. THE EARTH'S LANDFORM last but not least the main feature is 4.

Because oxygen is the last electron acceptor
The air that one breathes to keep electrons moving along from the first to the last chemical carrier is oxygen. Oxygen is necessary for all life forms to exist and enable existence. For instance, humans need the trees and plant life because they take in or breathe the carbon dioxide that humans expel, and then expel the oxygen that humans need to breathe in order to maintain life.
A person can last 4 minutes without oxygen, longer in extreme cold. It takes that long for the body to use up the oxygen in the blood.
Trees help to reduce global warming by 'cleaning the air'. Here's how: * A gas that helps to cause global warming is carbon dioxide. * Trees 'breathe' just like we do except when they breathe they take in carbon dioxide not oxygen. * When a tree breathes out it breathes out oxygen. * This is then breathed in by a human. * Carbon dioxide is breathed out the the human... * ...and breathed in by the tree... * This carries on continuously.
well they arent vulnerable like other trees their bristles protect them
Oxygen absorbers typically last about 1-2 years before they need to be replaced.
The duration a portable liquid oxygen tank lasts can vary based on the flow rate at which the oxygen is being used. Generally, a portable liquid oxygen tank can last anywhere from a few hours to a few days. It's important to consult with a healthcare provider or oxygen supplier to determine how long a specific tank will last based on individual oxygen needs.
