Nitrogen Cycle (3)

Process that add nitrate ion ions to the soil through lightning and volcanic eruptions (3)

This nitric acid seeps into the ground and reacts with minerals to form nitrate ions

Process that add nitrate ion ions to the soil through lightning and volcanic eruptions (4)

As a result, the quantity of nitrate ions in the soil increases

Process that add nitrate ion ions to the soil through nitrogen fixation (1)

Nitrogen-fixing bacteria in the soil, water or living symbiotically in legume plant root nodules convert nitrogen in the air into nitrate ions

Process that add nitrate ion ions to the soil through nitrogen fixation (2)

The resulting action of nitrogen-fixing bacteria increases nitrate ions in the soil

Process that add nitrate ion ions to the soil through nitrification (1)

When animals and plants die, decomposing bacteria convert animal protein and plant protein into ammonium compounds through the process of decomposition

Process that add nitrate ion ions to the soil through nitrification (2)

Then, nitrifying bacteria convert ammonium compounds into nitrite ions and then nitrate ions

Process that add nitrate ion ions to the soil through nitrification (3)

The resulting action of nitrifying bacteria on ammonium compounds increases nitrate ions in the soil

Processes that extract nitrate ions from the soil through process of absorbing nitrate ions from the soil (1)

Plants absorb nitrate ions from the soil to meet their nitrogen requirement

Processes that extract nitrate ions from the soil through process of absorbing nitrate ions from the soil (2)

These ions are used to form plant protein

Processes that extract nitrate ions from the soil through process of absorbing nitrate ions from the soil (3)

When animals eat plants, plant protein is transferred to the animals to form animal protein
