Correct Answer: They provide humus to the soil.

Solution : The correct option is They provide humus to the soil.

A fertiliser is an artificial substance containing elements such as Nitrogen (N), Phosphorus (P) and Potassium (K) that improve the growth and productivity of plants. The ideal use of N, P and K is 4: 2: 1. Humus is a dark, organic material formed by the decomposition of plant and animal matter in soil. It enriches soil structure, retains moisture, and enhances nutrient availability. Fertilisers, though rich in specific nutrients, lack the complex organic composition and soil-building qualities that humus provides.
