carbon dioxide
you breath in oxygen and release co2 or vise versa
yes oxygen is the gas that helps us breath without it we would die
This gas is oxygen from air.
Human beings breath in oxygen, and breath out CO2. The plant's leaves, when making photosynthesis, use CO2 and a few other things to make photosynthesis. When finished with making photosynthesis, the leaves release some oxygen, which is the gas we use to breathe. Thus, oxygen is the useful gas made by photosynthesis.
1) Helium, it's very light.2) Oxygen, it helps organisms breath.3) Carbon Dioxide, you breath this out of you. Plants take it in so they can release oxygen.
Oxygen
oxygen is plenty in nature
carbon dioxideNo.We breath in oxygen and breath out Carbon dioxcide.Now plants on the other hand, take in our waste, carbon dioxcide, and let out what we need, oxygen. thats why you may find the air fresher in a forest!
Correct, humans inhale oxygen and exhale carbon dioxide as a byproduct of cellular respiration. Oxygen is used in the process of breaking down glucose to produce energy in the form of ATP, resulting in the release of carbon dioxide as a waste product.
Because its part gas and we breath in oxygen
Because its part gas and we breath in oxygen
If you breath 100% Oxygen, it is not immediately poisonous and can be beneficial for a short time. However the human body has evolved to breath a gas mixture called air. Air is 80% Nitrogen and 20% Oxygen and if you breath a gas mixture significantly richer in Oxygen for a protracted period, then the Oxygen affects the functioning of most body systems and can lead to death. Also breathing Oxygen where the partial pressure of the Oxygen exceeds 1.2 bar, can cause acute oxygen poising resulting in convolutions. SCUBA divers need to take this into account when diving, especially on mixed gasses.
