ACTIVITY 014 - NITROGEN CYCLE
Nitrogen cycle
Nitrogen is one of the most important elements needed for plant growth. It occurs naturally in the atmosphere and in the soil.
The activity of soil micro-organisms transforms the nitrogen into various compounds so that plants can make use of it.
The nitrogen cycle is one of the most fundamental processes in nature. Without the action of soil bacteria, organic matter would not be decomposed and new plant growth would be reduced.
In the following diagram shows the Nitrogen Cycle in nature. Fill in the empty boxes with the correct processes and reaction taking place. You may find the answers from your notes or by browsing through the internet.
