Nitrogen & Phosphorus Cycles

Phosphorus is mainly found in rocks, sediments, and soil, not in the atmosphere.

Animals get nitrogen from the food they eat.

Phosphorus is mined from phosphorus-rich rock and is more localized compared to other biogeochemical cycles.

Yes, living organisms need phosphorus for various biological functions.

Bacteria fix nitrogen from the atmosphere into a form that plants can use.

Nitrogen is fixed through the action of bacteria and lightning.

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms, including fixation, nitrification, and denitrification.

Phosphorus is essential for DNA, RNA, and ATP, which are crucial for energy transfer and genetic information.

Nitrogen fixation is the conversion of atmospheric nitrogen into ammonia, while nitrification is the conversion of ammonia into nitrates.

The main forms of nitrogen available to plants are ammonium (NH4+) and nitrate (NO3-).
