Question

why do we only breathe oxygen why not carbon dioxide for surving??:/.​

Answer 1

Answer:

The carbon dioxide produced is a waste product and needs to be removed. Just like oxygen, carbon dioxide is transferred to blood to be carried to the lungs, where it is removed and we breathe it out.

Explanation:

All cells in our body need oxygen to create energy efficiently. When the cells create energy, however, they make carbon dioxide. We get oxygen by breathing in fresh air, and we remove carbon dioxide from the body by breathing out stale air.

hopefully it will helps you

BTW good evening...xD

Answer 2

we breathe in both carbon dioxide and oxygen but only oxygen is used in the process of respiration.

oxygen is the final electron acceptor in our body and oxygen is used to produce energy by breaking down of food we eat

CO2 will not accept electron because it is already stable and addition of electron make it unstable but oxygen can easily accept electron as it is more electronegative
