A hypoxic or anoxic zone
It is called organic matter
Saprophytic fungi
Decomposers release phosphorus into the soil from decaying animals and plants. Plants can now take up the phosphates in the soil. When animals eat the plants, they then have phosphates in them and they are released back into the soil through waste and decompostion (decaying).
Biogenic sedimentary
Nitrogen fixing bacteria make nitrates available for plants to use.
Millions of years of pressure and heat turned decaying animals and plants into coal.
Aquatic plants help to oxygenate the water - replacing the oxygen that's used by the fish - and the decaying fish waste.
oxygen can be formed by the electrolysis of water, or by chemical reactions Oxygen is present in air, about 19% by volume, but it is not formed there. Most oxygen is naturally formed in green plants and algea by photosynthesis.
plants and trees inhale carbon dioxide and exhale oxygen. The opposite of humans.
plants exrete carbon dioxide in the night time and exrete oxygen when light is available
Plants use Oxygen from the atmosphere and nutrients from the soil when no light is available for photosynthesis.

No, it's the other way around. Plants intake Carbon dioxide and put out Oxygen. In the theory of how the world formed, this is how the atmosphere got to contain Oxygen, from plants spreading over the continents and producing Oxygen.
