The only source of Oxygen is _____
The only source of Oxygen is _____
- Water
- Air
- Fire
- Trees
The main source of oxygen on Earth is photosynthesis, which is the process by which plants, algae, and some bacteria use energy from sunlight to produce oxygen from water and carbon dioxide. This process occurs in the chloroplasts of plant cells and is essential for maintaining the balance of oxygen in the Earth's atmosphere. In addition to photosynthesis, oxygen is also produced as a byproduct of certain chemical reactions, such as the decomposition of hydrogen peroxide. Finally, oxygen is also found in the Earth's atmosphere, where it makes up about 21% of the air we breathe.
Trees are a major source of oxygen on Earth. Through the process of photosynthesis, trees take in carbon dioxide from the air and use energy from sunlight to produce oxygen, which is then released back into the atmosphere. In this way, trees help to maintain the balance of oxygen in the Earth's atmosphere and provide a vital source of oxygen for all living organisms on the planet. In addition to producing oxygen, trees also play a number of other important roles in the environment, such as providing habitat for wildlife, helping to regulate the climate, and preventing soil erosion.
