Question

Many gardeners add earthworms to their soil if none are already living there. Why would gardeners do this?

A. Earthworms are useful to have when the gardener wants to go fishing.


B. Earthworms eat the roots of weeds, causing the weeds to die.

C. Earthworms release a chemical into the soil that acts as a natural pesticide.

D. Earthworms help to increase the fertility of soil.

Answer 1

The correct answer is D, earthworms eat the dirt, and then release it into the soil. They turn the dirt and soil into fertilizer so to speak. Worms also leave holes in the ground, which is good for water and air for the plants roots, but that isn't an option.
