• B. Fertilisers are naturally available in the environment.
• C. Fertilisers are mainly rich in N, P and K.

Answer 1

Answer: (A), (C)

Fertilisers are mainly rich in N, P and K.

• Fertilisers are man-made chemicals prepared in factories and are used in fields to enrich the soil with the required nutrients.
• They ensure a steady growth and development in plants as they are a good source of nutrients such as nitrogen, phosphorus, and potassium.
• However, long-term usage of chemical fertilisers decreases the fertility of the soil.
• Furthermore, they enter the food web through contaminated water and results in bio-magnification.
