Answer:
B)They help break down dead plant and animal matter.
Explanation:
The worms will join the worms to decompose the soil organic matter and allow various nutrients to be supplied to the plants. Decomposition of organic matter occurs as a result of worm metabolism.
In addition, worms "eat" the soil to form clumps, soil particles and humus that they later excrete. By forming aggregates, pores of various sizes are formed: thin pores that retain water within the aggregates and thick pores between the aggregates. Water drains rapidly from the large pores, allowing them to fill with air. In this way, soil aggregates provide the roots with the necessary water, nutrients and oxygen.
