The nitrogen cycle is a crucial natural process where nitrogen undergoes various transformations, transitioning between different forms in the environment.
It starts with nitrogen fixation, where bacteria convert atmospheric nitrogen into ammonia, making it accessible to plants.
- Assimilation occurs when plants absorb nitrogen compounds, entering the food chain.
- Decomposition releases nitrogen back into the soil, while nitrification converts ammonia into nitrates.
- Denitrification completes the cycle, returning nitrogen to the atmosphere.
This intricate process ensures a continuous supply of nitrogen, vital for the synthesis of proteins and nucleic acids, supporting life on Earth.
