Process that uses oxygen in the body?

Aerobic respiration is the process that uses oxygen in the body to produce energy. This process occurs in the mitochondria of cells and involves breaking down glucose to generate ATP, the primary energy source for cellular activities. Oxygen is the final electron acceptor in the electron transport chain during aerobic respiration.


What process uses carbon dioxide from the atmosphere?

The process of photosynthesis. Plants needs water and carbon dioxide to make oxygen and glucose this is called the process of photosynthesis.


What type of organism uses and produces both oxygen and carbon dioxide?

Plants are organisms that use carbon dioxide during photosynthesis to produce oxygen. They also use oxygen for respiration to break down sugars for energy.


Why does a candle turn off if you cover it?

Fire is a chemical reaction; it uses oxygen to turn one substance into another. If you cover it, it can't get any oxygen from the air, and so the chemical reaction stops and the fire goes out. I borrowed the following equation from another online Q&A as an illustration. When propane (carbon and hydrogen) burns, it combines with oxygen to make carbon dioxide (carbon and oxygen) and water (hydrogen and oxygen). C3H8 + 5O2 --> 3CO2 + 4H20


Does the Earth have an atmosphere, and if so, what are its key characteristics and functions"?

Yes, the Earth has an atmosphere. Its key characteristics include being composed of gases like nitrogen and oxygen, and having layers like the troposphere and stratosphere. The atmosphere functions to protect life on Earth by regulating temperature, providing oxygen for breathing, and shielding from harmful solar radiation.
