If you breathe in CO2 and breathe it out why do you need plants to change CO2 into oxygen?

The air that we inhale has approximately 78% nitrogen, 21% oxygen, and 0.04% carbon dioxide and approximately 1% inert gases.
The air that we exhale has 78% nitrogen gas, 17% oxygen, 4% carbon dioxide, and approximately 1% inert gases.
The difference between the amount of oxygen in inhaled and exhaled air is equal to the difference in the amount of carbon dioxide in exhaled and inhaled air.
Our cells need the oxygen produced by autotrophic organisms, such as cyanobacteria, phytoplankton, algae, and land plants. Photosynthesis is the only source of oxygen on the earth.
When we breathe in, gas exchange between the air and the blood takes place in the alveoli of the lungs. There, oxygen diffuses into the blood, making it oxygen-rich, and carbon dioxide diffuses out of the blood. Too much carbon dioxide is harmful, though some is necessary to maintain proper blood pH. The carbon dioxide that we breathe out is used by photosynthetic organisms for photosynthesis.

Why does plants breathe?
Why do people breathe ? Plants need oxygen too .
What are 3 reasons you need plants?
One reason is cuz u need it to breathe its photosythesis. We breathe out carbon dioxide plants breathe that in and breathe out oxygen which we breathe in. Without plants we would die.
Why do plants breathe out oxygen?
Oxygen is the end product of photosynthesis,plants need water and,some organic minerals from the soil,chlorophyll and carbon dioxide to undergo photosynthesis and the end product is oxygen which is need by the human.
Why are green plants important to oxygen?
Plants produce oxygen as a by-product of photosynthesis. Therefore, we, as animals who need oxygen to breathe, must have green plants in our ecosystem in order to survive.
What did Joseph priestly do in photosynthesis?
He observed and proved that plants release the oxygen we need to breathe.
Why do trees help us breathe?
We produce carbon dioxide which we release into the atmosphere when we exhale. Trees absorb the carbon dioxide and in turn produce oxygen, which we need to breath. Green plants are the world's best air purifiers!
Why forest is known as the green lungs of nature?
We breathe out CO2, trees breathe it in, they breathe out Oxygen and we breathe it in, so techincally they're our lungs
What resource is given off by plants in the carbon dioxide oxygen cycle and is necessary for the survival of animals?
Plants give off oxygen, which animals need to breathe.
Do plants need carbon dioxide to live?
No.Plants do not need carbon dioxide.But some plants use carbon dioxide during night and produce oxygen during day. Neem tree does not use carbon dioxide at all!!. They produce oxygen during the day as well as during the night.
What do you need to breathe in and out?
You need to breathe in oxygen and you need to breathe out carbon dioxide.
Why people need plants to change CO2 to oxygen?
Just like humans change oxygen to carbon. They need to breath
Why are the plants useful to us?
Plants and us Plants are our food, they improve our air and they are used to make many things that we need such as medicines, clothes and paper. Trees are cut down and the timber used to build houses and furniture. Plants are useful to us in many ways. We need oxygen in the air we breathe. Plants take in the carbon dioxide gas that we breathe out and turn it into oxygen. Plants keep the air we breathe stocked full of oxygen. Plants are food for us. They give the us the vitamins and minerals we need to grow and stay healthy. =) ~
