- Nitrogen cycle
- Atmospheric nitrogen gas (N2) cannot be used for plants to make proteins.
- Nitrogen fixing bacteria that live in the root nodules of the legume plants can convert the nitrogen gas into nitrate compounds (ammonia) through a process called nitrogen fixation.
- The ammonia from the lightning, fertiliser and nitrogen fixing bacteria is converted into nitrates by nitrifying bacteria.
- Plants absorb the nitrates to form protein.
- Animals eat the plants.
- Urea and egested material from the animal is broken down by decomposers to form ammonia back into the soil.
