A) 1 and 2 only
B) 1 and 3 only
C) 2 and 3 only
D) 1, 2 and 3
Correct Answer: A
Solution :
[a] Earthworms increases infiltration and not decrease them. Earthworms dramatically alter soil structure, water movement, nutrient dynamics, and plant growth. Stimulate microbial activity. Although earthworms derive their nutrition from microorganisms, many more microorganisms are present in their faeces or casts than in the organic matter that they consume. Earthworms enhance porosity as they move through the soil.
