Answer:

2. This gives the worms two separate populations of offspring that have different chances of surviving. An added benefit of being a hermaphrodite is that if a worm never finds a mate, it can fertilize its own eggs and reproduce that way. Many hermaphrodites experience this benefit.

3. Surprisingly, earthworms have quite a few digestive organs in common with humans. Digestion starts in the mouth, which takes in soil.

Explanation:

4. Worm castings contain the worms' gut bacteria and mucus. These microbes and substances are very helpful to plants. Vermicompost has more nitrogen-fixing bacteria than conventional compost. Vermicompost helps make minerals in the surrounding soil available to plants more quickly.
