How Does Temperature Effect Earthworms? Introduction When one thinks of earthworms usually one thinks about slimy and nasty creatures that are only used for fishing. Wrong! If there were no worms on earth, farms and many plants could not be properly maintained. This paper will explain how important earthworms are to the earth and to our environment. In addition, this paper will cover the origin of an earthworm, the anatomy and other important characteristics. Origin The origin of earthworms were said to be on earth around 200 millions ago. Their ancestors were marine worms, existing before there was even soil on this planet and vegetation. These worms underwent a slow process of adapting themselves to a new†¦show more content†¦Earthworms slowly bring soil to the surface and cover objects on the ground. This is one reason why archaeologists have to dig down underneath the ground to find fossils. Night crawlers burrows can go as far as 15 feet underground. Night crawlers have something that no other animal has. They have five pairs of hearts. The hearts pump blood with the earthworms muscular contractions. Only two main blood vessels make up the earthworms body. The ventral blood vessel sends blood to the rear end of the worm. The dorsal vessels pumps blood to the front end of the body and blood travels through the ventral vessels into the capillaries on the body wall and the many other organs. Anatomy The body of the earthworms is considered slimy and weird. Earthworms body contains 80% water and 70% protein. Fat makes up anywhere from 1 to 17 percent. The body divided into 100 segments. These segments contain a pair of metanephridia, which drain the adjacent anterior segments. The bristles help the earthworm hold its ground when trying to be pulled from its burrow. For instance, a bird pulls off 6 to 7 segments; therefore new segments will grow back. Earthworms are invertebrates, which mean they have no backbone. The mucus on the body helps the worm travel through their burrow smoothly. As the ea rthworm travels underground the mucus holds the dirt from collapsing on the worm.

The outside of the worm is divided into segements that is called primay segmentation. This means that the worm is divided by the longitudinal axis which is seperated by the septa and furrows. The Lumbricus species have an advantage when they are trying to tunnel and during locomotion by having retractile structures. Having these structures the species is ableRead MoreUtilization of Biodegradable Kitchen Wastes Into Organic Fertilizer Using Earthworms1247 Words   |  5 PagesUtilization of Biodegradable Kitchen Wastes into Organic Fertilizer Using Earthworms * Abstract One of the effective means to at least lessen the occurrence of our present garbage disposal problem is through the use of methods that are non-toxic, less expensive, less-harmful, and yet equally effective. This project aims to provide for a natural and effective way of disposing garbage. During the experiment, kitchen wastes were collected. The materials were shredded and placed in garbage bagsRead MoreEarthworms1384 Words   |  6 Pagesspiking in the treatment. However earthworms’ weights were affected by Cd concentration. (Maboeta et al., 2004; Spurgeon and Hopkin, 1996) have reported that as toxically resistant as they may be in a polluted environment, loss weight of earthworms was another sensibly factor due to the regulation of feeding rate in such environment. This observation was confirmed in this study by mixing rice straw in earthworms treatment which promoted great result in earthworms weight compared to the untreated potRead MoreComposting and Plant Growth1980 Words   |  8 Pages   Review of Related Literature HISTORY OF VERMICOMPOSTING Vermicomposting, as an industrial process, was originally developed to remove unwanted organic materials from the agricultural and industrial waste streams. The derived product: earthworm castings, is now recognized as a high value material which, when blended with soil, can restore soil tilth by correcting the imbalances caused by the over-utilization of petrol-chemical based fertilizers; thus enabling crops and plants to naturally combatRead MoreMeriton Ruhani.

Charles Darwin once said, â€Å"it may be doubted whether there are many other animals which have played so an important part in the history of the world, as have these lowly organized creatures.† He was referring to earthworms. The earthworm has been around for millions of years and can be found around the world.() Normally, when earthworms are mentioned, we immediately think of theRead MoreNew Zealand Flatworms Play a Huge Role in Agriculture820 Words   |  3 Pageslooked upon as a novelty in gardens around belfast and was not seen as a pest that could in the future potentially do detrimental damage to agricultural land. In 1983 scientists discovered that these flatworms were preying on our native types of earthworms, and drastic falls in their numbers were seen in areas where the NewZealand Flatworms were abundant.

Some organisms may share similar body systems while others have absolutely nothing in common. Several of those organisms include humans, pigs, crayfish, and earthworms. From their mushy, gushy organs to their soft, gentle skin, you may think, â€Å"How are humans and pigs possibly alike? Or a crayfish and an earthworm?† In many ways they may not be, but in other ways, they are very much alike. The body systems that will be compared and contrasted of these organisms are the nervous, circulatoryRead MoreFactors That Affect Soil Processes And Ecosystem Functioning760 Words   |  4 PagesSince the time of Darwin (1881), there has been a general perception that the earthworms are beneficial ecosystem engineers that significantly influence soil processes and ecosystem functioning. This has been shown in agricultural systems over the years, where earthworms increase nutrient transformation a nd plant nutrient uptake (Syers and Springett 1984; Edwards 2000). In addition, earthworms have been put to a use in organic waste management (Edwards 2000). Despite these beneficial effects in agricultureRead MoreStatistic Analysis : T Test1524 Words   |  7 PagesOverall, this experiment studies the influence of roughness, humidity and components on the behavior of earthworms. To test the impact of these factors, three experiments are designed with different independent variables; many variables are carefully controlled. Each experiment contains three groups, with five trials conducted for each group. With the raw data collected, which is the time each earthworm used to move through the roll or container of 50cm, the velocity is calculated as processed data. BasedRead MoreThe Environment Of A Soil Ecosystem1003 Words   |  5 Pagesenvironmental factors that affect the conservation and physiology of earthworms (M.L. Presley et al, 1996). Biological indicators can include earthw orms, plants, and leaf litter. Atmospheric indicators include carbon dioxide emissions. Interactions among these three indicators can also help to assess if the ecosystem is functioning. It is hypothesized that a functioning ecosystem is related to many types of interactions, such as earthworms eating leaf litter and leaf litter falling from the plants. It
