Question

How is the earthworm's digestive system related to segmentation?

Answer 1

A earthworm has a digestive system. It eats dirt, digesting the plant and animal matter in the dirt and then eliminates the rest. It has an esophagus for the food to go down, a crop to store the food in, a gizzard that grinds the food down, intestines for the food to pass through and take out nutrients and an anus for the food to come out.
A earthworm does not have a skeleton. It has bristles on each segment called setae that help the earthworm move. Earthworms have no limbs. The earthworm has two sets of muscles; one that makes it long and thin and one that makes it fat.
A earthworm has a nervous system with a simple brain and nerve cord.
A earthworm has blood and blood vessels with multiple (5) hearts.
A earthworm has no respiratory organ. It takes in oxygen directly through its skin and gives off carbon dioxide. Its skin is always moist.
A earthworm has both sperm and eggs within its body and reproduces sexually. However, the eggs must be fertilized by the sperm of another worm. An earthworm lays a batch of eggs at one time. They do not spend time raising their young once they are hatched
A earthworm's wastes help to fertilize the soil. It gets rid of its wastes through tubes called nephridin that lead to pores that allow the wastes out.
A earthworm has bilateral symmetry.
A earthworm is generally earthtones such as brown, tan, etc.. It can be up to eight feet in length!

Answer 2

An earthworm (Oligochaeta) is part of Phylum Annelida. Annelids have segmented bodies and segemented digestive systems. When the earthworm ingests food, the food has to go through many segments before excretion can occur. The digestive system is divided into these segements.

Answer 3

Segmentation leads to animals having different functions happening in different groups of segments. In the case of the earthworm, different parts of the digestive system are found in different groups of segments.

Answer 4

Earthworm "poo" is called humus. As we all know, segmentation is an old-fashioned idea of keeping people of different races apart so they don't socialize or inter-marry. So, the connection between the two is clear. No one wants to see mixed "poo". Some things are just against God's will and are deviant! So, as a result of rampant poo mixing, the Poo Pux Plan was developed by Calvin Coolidge during a mixer in North Dakota. I hope this helps. I searched web for hours to find this information for you!
