Question

• A. It makes soil porous
• B. Provides very good manure in the form of vermicompost
• C. Allows deep penetration of roots
• D. All of the above

Answer 1

The correct option is D All of the above

Earthworms help to increase the amount of air and water that gets into the soil. They break down organic matter, like leaves and grass into things that plants can use. When they eat, they leave behind castings that are a very valuable type of fertilizer. They help to turn the soil—bringing down organic matter from the top and mixing it with the soil below.

So the correct option is ' All of the above ' .
