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.
What else can I help you with?
Why is photosynthesis necessary in order for us to breathe?
Photosynthesis is necessary for us to breathe because it produces oxygen as a byproduct. During photosynthesis, plants take in carbon dioxide and water and convert them into glucose and oxygen using sunlight. The oxygen released by plants during this process is what we breathe in to survive. Without photosynthesis, oxygen levels in the atmosphere would significantly decrease and make it difficult for us to breathe.
How does the atmosphere preserve life on Earth?
There is oxygen in the atmosphere. This lets us breathe.
What changed your formerly poisonous atmosphere into an oxygen rich atmosphere?
The development of photosynthetic organisms, such as cyanobacteria and plants, played a significant role in changing Earth's atmosphere to oxygen-rich. These organisms released oxygen as a byproduct of photosynthesis, gradually increasing the oxygen levels in the atmosphere over millions of years.
What do plants give us back when you give them oxygen?
Plants release oxygen through a process called photosynthesis, where they use sunlight, water, and carbon dioxide to produce sugars for energy. The oxygen released during photosynthesis is essential for human and animal respiration, providing the air we need to breathe.
Why can and rsquot we breathe the oxygen from the earths crust?
We cannot breathe the oxygen from the Earth's crust because oxygen in the crust is primarily bound within minerals and rocks, not in its gaseous form. While the atmosphere contains free oxygen (O2) that we can inhale, the oxygen in the crust is typically part of compounds like silicates and oxides, which are not usable for respiration. Additionally, the oxygen in the atmosphere is released through processes like photosynthesis, making it accessible for us to breathe.
Do you breathe in oxygen?
Yes you do. See we breathe in oxygen and we breathe out carbon dioxide. Plants are the opposite. They breathe in carbon dioxide and breathe out oxygen. We give them carbon dioxide and they give us oxygen!! That's how we breathe!!!!!!!
What are the good effects of oxygen?
It helps us breathe
Why is oxygen useful to us?
We inhale oxygen for breathe. Also, animals and plants depend on it as well. It forms atmosphere so that air can stay on Earth and also a need of fire.
What do trees do for your earth?
they provide oxygen which helps us breathe
What plant saves lives?
All Plants save lives, as they all let us Breathe. As we breath in Oxygen, and Breathe out CO2, Plants are Breathing in our CO2 and Breathing Out Oxygen for us.
Why is air pollution negative?
because we breathe in the oxygen which is flowing around this earth and when we breathe in this oxygen around us ,we also breathe in air pollution which is not good for all things living on this planet.
What sort of air do bears breathe?
oxygen like us humans
Do tree need carbindioxsi?
Yes, trees need Carbon Dioxide. They breathe it in and exhale Oxygen for us to breathe.
What is a sentence with the word Breathe?
We need to breathe oxygen to live.He kept telling me to breathe easy. I'd like to see him breathing easy while giving birth.The oxygen tanks allow us to breathe underwater for a while.
Where do we get the oxygen from that we breathe in?
We get the oxygen we breathe in from the air. Oxygen is produced by plants during photosynthesis, where they take in carbon dioxide and water and produce oxygen as a byproduct. This oxygen is then released into the air for us to breathe.
Where do plants take oxygen from?
Plants do not take oxygen from anywhere. They absorb carbon dioxide from the air and release oxygen back out into the atmopshere. This is the opposite way round to us because we breathe in oxygen and breathe out carbon dioxide.
What is Carbendioxide?
Carbon Dioxede is the air that we breathe out.After that,the plants will breath in and gave us oxygen.Anyway,oxygen is the air that we breathe in.
