Summary Introduction

Introduction:

The nitrogen cycle is supplied with nitrogen from the atmosphere in the form of nitrogen gas and from the soil in the form of ammonia. The plants utilize nitrogen in the form of ammonia and nitrates. The human activity such as extensive use of fertilizers causes the changes in the nitrogen cycle. The fertilizers leach out to the water bodies that cause hypoxic conditions for the fish due to algal bloom.
