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.
The wormâs first segment contains its mouth. As they burrow, they consume soil, extracting nutrients from decomposing organic matter like leaves and roots. Earthworms are vital to soil health because they transport nutrients and minerals from below to the surface via their waste, and their tunnels aerate the ground.An earthworm can eat up to one third its body weight in a day. Night crawlers also mate on the surface. They are hermaphroditic but do not self-fertilize.he wormâs first segment contains its mouth.
