Organisms are constantly using the oxygen in the water and the oxygen is constantly reentering the water from the air Because of the oxygen cycle the amount of oxygen in the water remains relatively constant The oxygen cycle is important to maintain healthy ecosystems so that the rates of oxygen transfer and uptake in the water are balanced. An organism especially a bacterium that requires air or free oxygen for life. Free oxygen is oxygen that isnt combined with other elements such as carbon or nitrogen and aerobic organisms need it to live.
Oxygen gives our cells the ability to break down food in order to get the energy we need to survive. The appearance of free oxygen in the Earths atmosphere led to the Great Oxidation Event. This is one of the main suggestions I have come across for why a lack of oxygen is fatal to.
Humans get the oxygen they need by breathing through their nose and mouth into their lungs. How do animals obtain usable nitrogen. This from of respiration was more efficient and advantageous for land organisms.
Why are bacteria the most important part of the notrogen cycle. Animals take in oxygen when inhaling and give off carbon dioxide when exhaling. When the algae and seagrass die they decay.
Oxygen helps organisms grow reproduce and turn food into energy. The problem is that oxygen is like corrosive and was quite harmful to the early life. Living organisms generate energy from food through the process of respiration.
Oxygen destroys harmful bacteria in human bodies and is used to treat victims of carbon monoxide. Most mammals use lungs. All living things need nitrogen to build proteins and other important body chemicals.
The ATPs are the future reseve energy for all the vital works of the organisms. During this process of oxidation energy is released which is storedin the APT molecules. They also bring nitrogen back into the system by decomposing dead organisms.
Tatyana61 14 1 year ago. Why is free oxygen a problem for many organisms. An atmosphere containing free oxygen would be fatal to all origin of life schemes.
