The purpose of this experiment was to see how different foods affected the length of Lumbricus terrestris . The hypothesis was if Lumbricus terrestris eat celery, then they will grow longer than the Lumbricus terrestris eating carrot and worm food. Many know Lumbricus terrestris are fed worm food so they have the correct nutrients to grow. Three different foods were used in the experiment, celery, carrot and worm food. At first the Lumbricus terrestris eating worm food grew longer than the Lumbricus terrestris eating carrot and celery. Then after a few days the Lumbricus terrestris eating celery grew longer than any of the other Lumbricus terrestris. The results of this experiment supported the hypothesis, concluding that the Lumbricus terrestris that eat celery will grow more that the Lumbricus terrestris that eat carrot and worm food.
Purpose and Hypothesis The experiment was conducted to…show more content… From posterior to anterior, the basic shape of the Lumbricus terrestris is a cylindrical tube, divided into a series of segments (Monroe). The grooves that are normally externally visible are called "furrows". Furthermore Lumbricus terrestris have dorsal pores that secrete a fluid that keeps the skin wet and protects the worm's surface (Dadson). Except for the mouth and anal segments, each segment carries bristle-like hairs known as setae that are used for movement. Lumbricus terrestris play a large role in helping compost soil. In many soils, Lumbricus terrestris transform large pieces of organic matter into rich humus, which improves soil fertility. Lumbricus terrestris also aerate the soil by burrowing their wholes for their homes. This is achieved by the worm's actions of pulling below the surface, deposited organic matter such as fallen leaves or manure for food
