Oxygen is a vital gas that humans and most animals need to survive. We breathe in oxygen to help our bodies produce energy from the food we eat. Without oxygen, our cells cannot function properly, and life would not be possible.
Plants also play an important role by releasing oxygen into the air through photosynthesis. This continuous exchange of gases between plants and animals keeps the atmosphere balanced. Understanding oxygen’s role helps us appreciate the delicate system that supports life on Earth. Shutdown123
