Answer 2

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. Oxygen travels through the blood to all the cells in the body. The cells use oxygen to complete important jobs. For example, you are using oxygen right now as you read this sentence. The muscles that control your eyes use oxygen. Without oxygen, you could not \use any of your muscles. In fact, our cells die quickly if they do not receive oxygen. That is why it is so important to help someone who cannot breathe by providing them with oxygen.Plants and other organisms that perform photosynthesis rely on animals for carbon dioxide.
