Question

How is CO2 essential for life

Answer 1

hey dear your answer'-:-) -''''---'-:-) :-)




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.'-:-) :-) -------:-) :-) :-) :-) ---

The carbon dioxide and oxygen cycle is critical to life on Earth. Humans, and most other organisms, need oxygen to survive. When we inhale, oxygen moves from our lungs into our blood. ... In fact, our cells die quickly if they do not receive oxygen.':-) :-) :-) :-) :-)
