Answer:
(a) Grass, dry leaves and urine/excrete of animals
option (a) is the correct answer.
Explanation:
Biofertilizers are made naturally from organic materials like plants and animal feces. These produce microorganisms that provide nutrition to the soil and help in plant growth.
The three types of biofertilizers are bacteria, fungi, and cyanobacteria. Biofertilizers are eco-friendly and do not pollute the soil whereas excessive use of chemical fertilizers pollutes the soil.
