All living plants and animals need nitrogen for their growth as it is an important constituent of proteins.
Why plants need Nitrogen?
Nutrition is the mode of taking food by an organism and its utilisation by the body. Nitrogen is a crucially important component of all life. Nitrogen is a naturally occurring element that is essential for growth and reproduction in both plants and animals. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits.
