An abscessed tooth is an infection within a tooth that has spread to the root tip or around the root. This infection originates from the tooth's inner chamber, which is called the pulp chamber.. Contained within the pulp chamber are blood vessels and nerves, collectively called the pulp..
Earthworms prefer to eat at night, though, rather than in the day. That is why they are also called nightcrawlers. Besides adding nutrients to the soil, earthworms keep the soil healthy by tunneling. Worms do not have claws or paws to make tunnels, but they do have mouths. As they eat (and eat and eat), they create tunnels that keep the soil open and full of paths for water and air.
Instead of teeth, earthworms have a gizzard like a chicken that grinds the soil and organic matter that they consume. Their main intent is to eat the soil microorganisms that live in and on the soil and organic matter. Worm excrement is commonly called worm casts or castings.arthworms are part of a host of organisms that decompose organic matter in the soil. As earthworms digest the microorganisms and organic matter in soil, the form of nutrients is changed as materials pass through the earthwormâs gut.
