Why is the atmosphere is essential for life
Answers
It is important because we can't live without air.
In atmosphere there is 22 %of oxygen takes place.78% is nitrogen.0. 03% in atmosphere other gases are there.
without oxygen in atmosphere photosynthesis do not take place.
we are not able to survive.
Answer:
Why is Earth the only planet in the solar system known to have life? The main reason is Earth’s atmosphere. Organisms need the gases in the atmosphere to live. Water is also essential for life. Water vapor is one of the gases in the atmosphere. Green algae, like in this photo, are primitive life.
The Atmosphere
The atmosphere is a mixture of gases that surrounds the planet. We also call it air. The gases in the atmosphere include nitrogen, oxygen, and carbon dioxide. Along with water vapor, the atmosphere allows life to survive. Without it, Earth would be a harsh, barren world.
The Atmosphere's Importance
We are lucky to have an atmosphere on Earth. The atmosphere supports life and is also needed for the water cycle and weather. The gases of the atmosphere even allow us to hear.
The Atmosphere and Living Things
Most of the atmosphere is nitrogen, but it doesn't do much. Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life.
Plants need carbon dioxide for photosynthesis. They use sunlight to change carbon dioxide and water into food. The process releases oxygen. Without photosynthesis, there would be very little oxygen in the air.
Other living things depend on plants for food. These organisms need the oxygen plants release to get energy out of the food. Even plants need oxygen for this purpose.
The Atmosphere and the Sun’s Rays
The atmosphere protects living things from the Sun’s most harmful rays. Gases reflect or absorb the strongest rays of sunlight
