Question

Answer 1

Without the atmosphere, Earth would be lifeless. Carbon dioxide (CO2) and oxygen(O2) are the most important gases for living organisms. CO2 is vital for use by plants in photosynthesis, in which plants use CO2and water to convert the Sun's energy into food energy.

Answer 2

Explanation:

The atmosphere of Earth, commonly known as air, is the layer of gases retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation).
