Question

why there is carbon dioxide present in the air.? Why cannot we take carbon dioxide why we need oxygen?​

Answer 1

$\huge\mathfrak\red{Answer}$

• Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. ... Respiration, the process by which organisms liberate energy from food, emits carbon dioxide. When you exhale, it is carbon dioxide (amongst other gases) that you breathe out.
• With sugars and oxygen, our cells can create the energy they need to function. ... This is important because if we couldn't remove carbon dioxide from our blood, it would take up all the carrying capacity of our blood and we wouldn't be able to get oxygen to the rest of our body.
