Earthworms (Phylum - Annelida, Class - Chaetopoda, Order - Oligochaeta) occupy a unique position in animal kingdom and are the first group of multi cellular and eucoelomate invertebrates who have succeeded to inhabit terrestrial environment. The knowledge about the importance of earthworms is not a very modern phenomenon. The Ancient Greeks regarded the earthworm to play an important role in improving the quality of the soil. The Greek philosopher Aristotle (384 – 322 B.C.) regarded worms as “the
these celebrities? The common-or-garden earthworm. Because you will see, earthworms should be respected. True, they're slimy plus they wriggle. But even these characteristics, which we may consider unattractive, can inspire a feeling of awe when you become familiar with the earthworm just a little better. All that you should do is bend lower and upturn a clod of soil or disturb a layer of leaf litter, and you've got joined the fascinating realm of earthworms. Simple Brain, Astounding Talents Take
The Lumbricus Terrestris is the scientific term for the common Earthworm, and is otherwise known in the United States as the Nightcrawler. Earning this name due their habit of not appearing above ground to eat until the dark hours of the day, these segmented worms made up of annuli have the ability to dig six and a half feet deep into the soil. They commonly become seven to eight centimeters in length, and spend a lot of their time eating using their mouth which is located in the first segment of
if the end isn’t what I thought it would be? All the times that I stumbled and fell and picked myself up and kept running, kept running with bruises and pain and a heart tinted with shadows of doubt, kept sprinting towards the unknown just as the earthworm does, that would all go to waste. And I would be left lost, irreparably broken by regret at the lifetime I wasted. It’s this fear that makes me weak and sucks out the will to go forward. I don’t know how close my dreams are. They could be dancing

Adams' Grammar School Murder Mystery Chapter 1: The Death Of An Earthworm A new day dawned on Adams' Grammar School. It was a Tuesday in early March, bright with the promise of Spring. The sunlight glinted off the golden hands of the ancient school clock, momentarily dazzling Mr R. Jones, veteran teacher of history, as he moved busily about the
Abstract The medicinal value of earthworms has been known for centuries. The earthworms are the source of proteins, peptides, enzymes and physiologically active substances. Thus in the present study, the earthworm skin extracts were prepared and subjected to antimicrobial activity which was determined by the agar well diffusion method. The antimicrobial substances showed activity against Serratia marcescens. The molecular weight of the peptide from skin extract was found to be ~3kDa by SDS – PAGE
Earthworms are important components within ecosystem functionality and play a vital role in soil nutrition and fertility. (Edwards 2004). A prominent characteristic of earthworms is their ability to respire through diffusion of their skin (Bharambe et al 2008). As a direct result of this, earthworms are typically found in moist soils. (Roots 1956). The moist soil is vital in creating the ideal conditions for earthworms to maintain the hydrostatic pressure needed to respire (Laverack, 1963). Although
1.4 Sawdust The production of briquettes from sawdust and other agro-residues exemplifies the potential of appropriate technology for the utilisation of biomass residues which abound in large quantities in developing countries. However, compared to developed countries where successful briquette operations are mostly found, briquettes have not been widely adopted in developing countries due to the high cost of production, lack of awareness on its sustainability, lack of ready market and poor packaging
Introduction Earthworms live in soil and get nutrients from eating the dirt and can eat ⅓ of its body weight, if they get too cold they will freeze and die.(Mrs. Harrison, 2017) When they are in the ground they go as far as 2 meters under and when they are getting cold they can go down further. (Journey North, Uknown time) This lab is important because it will help us understand how worms react to different temperatures of water. All earthworms live in the 2 to 3 inches of soil
pull earthworms out of the ground to eat. They also enjoy the forest like surroundings and the wilderness areas. They usually migrate as far as to Canada during the American winter, and they migrate back when spring comes. You notice that Robins disappear in the winter and show back up in the spring. This is because they enjoy the warmer spring like temperatures. Place Located on the Food Web (2) The American Robin is close to the top of its food chain. The bird relies on Earthworms, crickets
is then turned into energy for the organism. The earthworm digestive system is one of the simplest digestive systems compared to the frog or a human. The digestive system is section off into certain parts and each part has a certain function in the digestive process. The earthworm’s digestive system consists of the pharynx, the esophagus, crop, the intestine, and the gizzard. Each organ has a specific contribution to the digestion in an earthworm. The food, which is usually soil, passes through the
is my review of "James and the Giant Peach" performed at the Blue Orange Theatre. This review is predicated on the performance which I observed on Tuesday 2nd June 2015. The play consisted of the following characters: Centipede, Lady Bug, James, Earthworm, Miss Spider, Old Green Grasshopper and the two aunts (Aunt Spiker and Aunt Sponge). The type of staging used was proscenium staging hence the audience was in front of the performers. The unique performance stage suited the production if you were

Many Much of the data concerning the effects of radiation on earthworms are derived from field studies in which, radionuclide activities in soil have been increased by artificial contamination or by field monitoring after nuclear accidents. These studies have shown effects such as reduced population size, changes in
belief for Buddhists. In the movie, Heinrich was building a movie theatre for the Dalai Lama. The townspeople were helping them, but while they were digging they noticed earthworms were living there. It would be cruel for them to kill the earthworms; so in order to build the movie theatre they must remove all of the earthworms and put them somewhere else to live. In the novel, Siddhartha always had respect for nature. The river is an object that meant a great deal to him. Siddhartha could never
No eyeballs, no earthworms. Despite this, many people continue to spread and believe horror stories they hear regarding McDonald’s burger recipe. Regardless of the fact that there is no evidence to support these claims, the distrust for the large franchise is so great that
Absence of circulatory system Circulatory systems are absent in some animals, including flatworms and unicellular animals. Flatworms lack enclosed fluid or lining in their body cavity, but a muscular pharynx instead that leads to an extensively branched digestive system where nutrients and oxygen diffuse directly to all cells with ease. This is enabled by the reduced distance of body cells from the digestive system because of the flatworm’s dorso-ventrally flattened body shape. Thus every cell obtains
Natural Farming products have high quality, good taste and better yield. People commonly think that by converting to organic farming you will have smaller yields, lower quality and smaller-sized fruits. In Natural Farming it is the opposite. We do not go back to the past; we take a leap into the future. Natural Farming products have much higher nutritional contents. Protein, amino acid, crude fat and other essential nutrient were identified to be as much as 300 percent higher than ordinary products
An example of a closed circulatory system could be earthworms and fish. In these organisms there are oxygen carrying pigments which is called haemoglobin and haemocyanin which is found within the vessels and around the body cavity. The heart creates a high blood pressure which is the system that moves the
some of the others, because I was not only taking Biology, but I was taking college prep Biology. The only drawback to the class was I was going to have to a lot of dissecting to do. Now, I know in Biology everyone had to dissect the traditional earthworms and frogs, which I can handle without any problems. The problem I encountered after I entered the Biology class was not the fact that I had to dissect worms and frogs, but I had to actually dissect a fetal pig. I was not looking forward to this
Non-liquid material discarded as useless finally piles up as solid waste generating unwanted toxicity affecting Mother Earth and her environment. A quote of British author and playwright, Diane Samuels flashes in mind, “You mustn’t throw them away. Let me have them.” So, the solution is reuse and recycle. Let’s see how. Benefit of Recycled Waste Firstly, the biodegradable waste needs to be segregated from the non-biodegradable ones. The further steps discussed here is taken forward with the biodegradable
