The real short answer is that Oxygen is the electron receptor, some species use sulfur. The long answer is oxidative metabolism. Oxygen is to be used in the release of energy from glucose during respiration.
because it is a gas that helps living life forms such as us and animals survive. and the stuff we breath out is carbon dioxide which is also necessary because plant breathe that in and breathe out oxeygen which helps us survive. that why its necessary and that's why we need plants.
Also, symbollically, it seems to be the essence of 'the breath of life', which God breathed into Man upon his creation.
Oxygen is needed to survive . Without oxygen , all living things can't survive . All living things needed 3 things to survive . They are air , food and water . Without this three things , no living things can survive .
Well its because you need oxygen throughout your body including your blood stream and if you don't have any oxygen in your body you die bc also all your major organs
Oxygen is required for aerobic cellular respiration. Without oxygen we would not be able to get enough energy from food to survive.
To survive We get oxygen from trees
so you can breathe
it is because catfish can survive in low-oxygen levels. Trout survives at higher oxygen levels
oxygen was created by trees.Trees were created from bacteria and living organisms.Trees create oxygen that we need to survive.
needed by most organisms in the process of
we survive by oxygen from trees water and eviornment!

oxygen
Yes - oxygen is needed for cellular respiration, which is vital for cells to survive.
Fish need oxygen to live.
There are various functions of oxygen. For example, the most obvious is that it is needed for humans and other animals to survive.
Organisms that require oxygen depend on the oxygen in the air, which was put there by plants.
No. Oxygen is produced as a waste product of photosynthesis and is excreted from the plant as it is not needed by the plant.
because oxygen is needed for cellular respiration and deep waterdoesnot contain oxygen
no.
Oxygen is used for producing energy in your body. None of your body's cells can survive long without oxygen. Oxygen is needed for practically every single chemical reaction in your body.
Facultative anaerobes can survive without oxygen but will use oxygen if it is present.
If they CAN survive without oxygen, they are called facultative anaerobes. In other words, these can survive with or without oxygen.If they CAN ONLY survive if there is no oxygen, they are callled obligate anaerobes. In other words, these can only survive if there is no oxygen.
Plants need oxygen in order to survive, and is a part of the photosynthesis process. Plants also need carbon dioxide and nitrogen to survive.
