Answer 2

Explanation:

As the supply of essential nutrients is reduced, then the plants exhibit a particular symptom which differs from plants to plants.

In certain cases,

(1 )If the deficiency elements are relatively mobile, like nitrogen then the first deficiency symptoms appear in the older tissues of the plant and then followed with the younger tissues.

(2). If the deficiency elements are relatively immobile and are not transported out of the mature organs, then the first symptoms tend to appear in the younger tissues and then followed with the older tissues.

The deficiency symptoms are varied and include, stunted plant growth, premature fall of leaves and buds, yellowing of leaves, etc. These symptoms could be caused due to the lack of both micronutrients and macronutrients in plants.

There are a few essential minerals required for plants growth and development. Hence, the deficiency of such essential minerals, namely – iron, nitrogen, manganese, potassium, magnesium, zinc, calcium, results in deficiency symptoms

It must also be kept in mind that different plants respond to different deficiencies, differently.
