The correct answer is A) oxygen. Oxygen is the other product of photosynthesis that is responsible for our atmosphere as we know it today. During photosynthesis, plants and some other organisms use carbon dioxide and sunlight to produce glucose and release oxygen into the atmosphere as a byproduct. The accumulation of oxygen over millions of years by photosynthetic organisms has significantly transformed the composition of Earth's atmosphere, allowing aerobic organisms like humans to thrive.
The correct answer is A) oxygen. Oxygen is the other main product of photosynthesis that is responsible for shaping our atmosphere as we know it today. Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose (a simple sugar) and oxygen using sunlight. While glucose serves as an energy source for the plant, the oxygen is released into the atmosphere. Over billions of years, the accumulation of oxygen from photosynthesis by plants has greatly increased the amount of oxygen in Earth's atmosphere. Oxygen makes up about 21% of Earth's atmosphere and is vital for the survival of many forms of life, including humans.
