We breath it! It goes in through our mouths and out through our tushie and mouth!
Oxygen is important to human body because it aid in breathing
plants and animals.
Humans (and most, and if, not all other organisms) need nitrogen is to produce protein. Oxygen is used up in respiration to help produce energy used by the human (and other organisms, but not plants) body.
Some common compounds of oxygen include water (H2O), carbon dioxide (CO2), and ozone (O3). Water is essential for life and is used in various industrial processes. Carbon dioxide is important for photosynthesis and is also used in carbonated beverages and fire extinguishers. Ozone is used to disinfect water and air, as well as in some industrial processes.
Oxygen is important cells as without oxygen the human body is unable to release enough energy to support life. In theory any other element in the oxygen-group on the Periodic Table can be used to release energy but because other elements in that group are not easily turned into gases they can't used. Last comment; Oxygen is not important for blood; its important for the blood cells themselves and other cells. Blood and blood cells are very different.
The most important thing about trees is they produce oxygen and we need oxygen to live, no oxygen no life. Also trees are important because: they produce food - fruit and nuts they can be used for housing and building other things - boats they can be used for fuel
Oxygen is important to humans so we can breathe. we then give off carbon dioxide which plants need. Plants give off oxygen and the cycle repeats.
During respiration Oxygen is used & CO2 is released.& during photosynthesis CO2 is used & oxygen is released.Therefore when these 2 processes are balanced the O2 & CO2 concentration of the planet will be balanced too.
Oxygen is primarily used in society for medical purposes to help patients with breathing difficulties, in industries for various processes like cutting and welding, and in water treatment plants for purification processes. Additionally, it is used in the production of steel, glass, and chemicals.
Oxygen is essential for respiration in animals and humans, as it helps produce energy for cells. It is also important in combustion reactions, such as in fire and engines. In addition, oxygen is used in various industrial processes, such as in steel production and water treatment.
Oxygen and Carbon Dioxide
Plastic itself does not contain oxygen as an element within its molecular structure. However, during the production process of plastic, oxygen may be used as a reactant or in other chemical processes.
