Because we breathe it in. If we couldn't breathe, we'd suffocate and die.
Oxygen is the most important factor for living things.
Oxygen is important because it permits us to live
oxygen
Plants produce oxygen during photosynthesis, which is vital for the survival of all living organisms. Oxygen is needed for cellular respiration, a process that releases energy for living organisms to carry out their functions.

oxygen and carbon dioxide are the 2 most important gases for living things
Both oxygen and nitrogen are equally important to living things. Oxygen is necessary for metabolism to continue. But too much oxygen is poisonous. So the presence of nitrogen keeps the oxygen levels low enough to avoid poisoning.
Plants are essential for living things. Plants produce oxygen through a process called photosynthesis. Without plants, there would not be enough oxygen on the planet for all living things to survive. Plants are also a critical part of the food chain.
Carbon, hydrogen, nitrogen, oxygen, phosphorous and sulfur.

For me the ecosystem is the place were living the living things and non living things and the importance of it to as is that they are produce the oxygen that we are in healing
The gases of the environment are important to all living things because they help them in various processes. For instance animals need oxygen for respiration while the plants need carbon dioxide for photosynthesis.
