Question

Earthworm, a friend of farmer, belongs to the phylum _______.

• A. Arthropoda
• B. Echinodermata
• C. Mollusca
• D. Annelids

Answer 1

The correct option is D Annelids

Earthworms are the segmented worms that belong to the phylum Annelida. Earthworms are called the 'friends of farmers' because they help in increasing the fertility of the soil. These worms feed on the soil and degrade the matter in the soil. This leads to the production of humus. The presence of humus (rich in organic matter and nutrients) increases the quality of the soil.

Thus, the correct answer is option D.
