How does Carbon Dioxide in Earth’s atmosphere allow Earth to support life?
A
Animals need Carbon Dioxide to breathe.
B
Carbon Dioxide traps radiation from the sun to warm Earth and is used by plants in photosynthesis.
C
Carbon Dioxide is produced by plants so that animals can breathe.
D
Carbon Dioxide is needed to make water.
Explanation: 

Detailed explanation-1: -Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. However, an increase in CO2 concentrations in our atmosphere is causing average global temperatures to rise, disrupting other aspects of Earth’s climate.

Detailed explanation-2: -Scientists have determined that carbon dioxide’s warming effect helps stabilize Earth’s atmosphere. Remove carbon dioxide, and the terrestrial greenhouse effect would collapse. Without carbon dioxide, Earth’s surface would be some 33°C (59°F) cooler.

Detailed explanation-3: -What Are Greenhouse Gases? Earth’s greenhouse gases trap heat in the atmosphere and warm the planet. The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor (which are all natural compounds), and fluorinated gases (which are synthetic or man-made).
