1 decomposition by bacteria & fungi
Nitrogen in the air nitrogen fixing plant eg pea, clover animal protein plant made protein dead rabbit dead plants & animals urine & faeces denitrifying bacteria root nodules (containing nitrogen fixing bacteria) decomposition by bacteria & fungi nitrates absorbed nitrates ammonia bacteria nitrites bacteria (nitrifying bacteria)
