1 decomposition by bacteria & fungi
Nitrogen in the air nitrogen fixing plant eg pea, clover animal protein plant made protein 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) This Powerpoint is hosted on Please visit for free powerpoints

2 The nitrogen fixing bacteria are found inlumps on the roots called root nodules. The bacteria and the plant have a symbiotic relationship: the bacteria benefits by having food and shelter from the plant and the plant benefits by having nitrates produced by the bacteria. Roots of a legume plant (peas, beans and clover).

Living thing require nutrient cycles ( nitrogen cycle) because - Some organism ( decomposers) obtain energy from the break down of dead bodies and waste.
