Why must nitrogen be "fixed"

So it can be used by plants and animals, the gas in the air can not be used until then.

What does biogeochemical cycles mean? Break up the word!

Bio- life

Geo- Earth

Biogeochemical cycles, also known as nutrient cycles, are the processes that move chemical elements and compounds between the Earth's atmosphere, crust, and living organisms. These cycles involve biological, geological, and chemical processes that regulate the movement of elements within the Earth's environment and ecosystems.
