How do we eat?

If you had to name an animal less like a human, worms would probably top your list. They're small, slimy, have no bones, and live in the dirt. But as different as they are from people, they can't escape the need to feed! Worms are detritivores, or animals that eat decaying matter. They have a mouth on one end, that they open up and let the soil fill their pharynx, where they swallow like our throat. This soil has minerals, dirt, and decaying organic matter like dead plants and bugs. After that, the food passes through the esophagus and is stored in the crop before moving to the gizzard. Inside the gizzard, tiny stones crush and grind food until it's ready to digest. Now the food is ready to move through the intestine, a long tube that runs the majority of length of the worm.  Inside the intestine, the worm uses digestive chemicals to break down and absorb the nutrients. Then the food exits the worm as "castings." Worm castings make for excellent fertilizer and are great in nature and in your garden.
