The Amazon rainforest, along with the central African region rainforest (in addition to heavily forested areas in other parts of the world). After all, plants take in CO2 and give off oxygen.
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.

Plants are a primary source of carbon and oxygen through the process of photosynthesis, where they take in carbon dioxide from the air and convert it into glucose, releasing oxygen as a byproduct.
The primary source of oxygen in Earth's atmosphere comes from photosynthesis by plants, algae, and some bacteria. During this process, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This oxygen is then released into the atmosphere as a byproduct.
The primary source of Earth's atmosphere is outgassing from volcanic activity and the release of gases from Earth's interior. This process began billions of years ago and continues to contribute to the composition of our atmosphere.
The primary source of Earth's oxygen is through the process of photosynthesis carried out by plants, algae, and cyanobacteria. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Additionally, a small amount of oxygen is produced through chemical reactions in the atmosphere.
The Sun is Earth's primary source of light energy. It emits light in the form of electromagnetic radiation that reaches Earth and provides energy for various processes such as photosynthesis and heating the planet.
The Sun is Earth's primary external energy source. Solar radiation emitted by the Sun provides heat and light energy to sustain life on Earth through a process called photosynthesis.
The Sun is Earth's primary source of light energy. The Sun emits electromagnetic radiation, including visible light, which provides energy for photosynthesis and powers many processes on Earth.
It is a primary source.
