Question

Carbon dioxide is an important give reason

Answer 1

Answer:

Carbon dioxide is important because plant prepare their food with the help of CO2. It is a greenhouse gas and keep the earth temperature warm by trapping heat.

Answer 2

Two main reasons are :

Reason 1:

carbon dioxide is one of the most important gases on Earth. Plants use carbon dioxide to produce carbohydrates (sugars and starches) in the process known as photosynthesis. (In photosynthesis, plants make use of light to break down chemical compounds and produce energy.) Since humans and all other animals depend on plants for their food, photosynthesis is necessary for the survival of all life on Earth.

Reason 2:

Carbon dioxide in the atmosphere is also important because it captures heat radiated from Earth's surface. That heat keeps the planet warm enough for plant and animal (including human) life to survive. Increasing levels of carbon dioxide in the atmosphere may be responsible for long-term changes in Earth's climate. Those changes may have both beneficial and harmful effects on human and other forms of life on the planet.
