trees and plants also algae...trees take in carbon dioxide and release oxygen into the atmosphere .....so destroying trees effects the amount of oxygen in the air which then leads to global warming ....
The Earth is the only planet with a large quantity of free oxygen, which came about because of plant life, which uses carbon dioxide and energy from the Sun to manufacture carbon for plant tissues, giving out oxygen as a waste product. About 21% of the Earth's atmosphere is oxygen.
The life-giving gas is oxygen. Oxygen is essential for the survival of most living organisms as it is used for cellular respiration to produce energy.
Oxygen usually exists as a diatomic molecule, O2, in the Earth's atmosphere.
Oxygen is the most common and abundant element in the Earth's crust having 47% of the mass.
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
The Earth is the only planet with a large quantity of free oxygen, which came about because of plant life, which uses carbon dioxide and energy from the Sun to manufacture carbon for plant tissues, giving out oxygen as a waste product. About 21% of the Earth's atmosphere is oxygen.
Earth is the only planet known to have a significant amount of oxygen in its atmosphere. Other planets within our solar system either have trace amounts of oxygen or it is mainly bound up in compounds like water or carbon dioxide.
Oxygen is essential for the process of respiration in living organisms, allowing them to produce energy from food. Without oxygen, aerobic organisms would not be able to survive. In addition, oxygen is a key component in the formation of water, a crucial compound for life on Earth.
there would be nothing giving us oxygen and every living thing would suffocate.
the sun contributes to earth by giving everything life. plant require sun to cause the carbon cycle in which the plants then produce oxygen in which we and animals need to survive.
Oxygen is main gas of earth. If there is no oxygen in the earth all the life in the earth should die.
there would be nothing giving us oxygen and every living thing would suffocate.
we get oxygen from the trees
Earth's atmosphere, including the oxygen, is bound to Earth by gravity.
The life-giving gas is oxygen. Oxygen is essential for the survival of most living organisms as it is used for cellular respiration to produce energy.
There is oxygen and gravitational force on earth but there is no oxygen and gravitational force
About 21% of the Earth's atmosphere is composed of oxygen.
