Earthworm Research Paper

Gut worms are a type of roundworm that infect cattle in their stomach by causing eggs to form in their feces. Also known as Parasitic Gastroenteritis (PGE), this disease causes the cattle industry to lose millions of dollars each year.

Earthworms help solve this problem by bringing the pH closer to 7, allowing for microbial growth of bacteria. After an earthworm consumes organic matter, it releases casts, the which are the feces of the worm. Earthworm casts have higher available nitrogen, phosphorus, and potassium contents at a ratio of 3.2-1.1-1.5, than surrounding soil and contain helpful microbial enzymes. The earthworm casts have higher micronutrient content or higher contents of nitrogen and phosphorus due to the bacteria residing in the digestive tracts of the earthworms. The bacteria in the digestive tracts of earthworms speed up the decomposition of organic material such as decaying plant matter and unlocks the minerals that were trapped.

Fish are aquatic animals meaning they cannot live on land as there is no water. Water’s dissolved oxygen percentage is much lower (1%) than that of air (20%). Because fish live in water, their gas exchange process is much different to that of mammals. A fish breaths by opening its mouth as it swims and allowing water to flow over its gills. When the fish opens its mouth the opercula close meaning water is able to flow over the gills and oxygen can be drawn from the water and carbon dioxide can be expelled. Water flows out of the fish when it closes its mouth allowing the opercula to

If mealworms are attracted to moisture, and tend to move away from hardened food, why would the mealworm move towards bran flakes and begin to go inside the pile.

Secondly, the human body, crayfish, earthworm, and frog also have many similarities and differenced of how their respiratory system works. The crayfish respiratory system is the least complex. Crayfish have gills, which are used to release carbon dioxide and to pick up oxygen, by having a constant flow of blood. Frogs consist of nostrils and larynx, which opens up two lungs. The walls of the lungs are filled with capillaries. Capillaries are

All organisms in the world have a range of systems and organs in their body. 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, “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, circulatory, reproductive, muscular, integumentary, digestive, excretory, and skeletal systems.

species group. The location of this earthworm was in Australia, where they claimed their habitat

When society thinks about crayfish and earthworms they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of both animals before going into major detail about them. According to the online website named dictionary.com, it says that an earthworm is a burrowing annelid worm that lives in the soil. Earthworms play an important role in aerating and draining the soil and in burying organic matter (Dictionary). Crayfish are nocturnal freshwater crustacean that resembles a small lobster and inhabits in streams and rivers (Dictionary). Crayfish and earthworms are some very interesting animals that possess some exclusive qualities both similar and different.

They play a key role in regenerating and displacing soil. Earthworm activities changes both physical and chemical characteristic of soil. They help convert organic matter to humus. Additionally, they ingest other particles (sand grains) and when it is digested and excreted, it is accessible for plants to take advantage of its minerals and nutrients. Physically, the earthworm creates tunnels for air and water to navigate the soil. () They play an essential role in fighting erosion and are vital to plant growth. Healthy soil is depended on a thriving worm population. The ability to break down organic matter and excrete nutrients makes the earthworm valuable to restoration projects. Some people have employed earthworms to prepare soil for the return of native flora. Individuals that utilized this idea have seen better results in the return of their soil ecosystem than previously used methods. The number of

Heartworm disease can be fatal to your furry friend if it is left untreated. Foot-long worms are found living in the heart, lungs, and associated blood vessels. These worms can cause severe damage in organs as well as cause lung disease and heart failure. This disease has been found to affect dogs, cats, ferrets, wolves, coyotes, foxes, and sea lions. Which the information I learned from my research, I will be discussing the history of heartworm, what causes it, the symptoms and clinical signs, how to diagnose it, the treatment need, as well as preventing it.

Purpose: We want to see if putting a worm or organism in different temperature will change the rate of CO2. We predict cold will make the process slow down. Hot will speed it up, and with room

Imagine you are at the bottom of the ocean, and there are hydrothermal vents ejecting hot lava. Adding to your misery, there are huge amounts of hydrogen sulfide gas everywhere that are poisonous to your body. In reality, this is the giant tube worm’s ecosystem. Ecosystems are all of the living things (plants/animals) and the non-living things that live in a specific area and interact with each other. Ecosystems can be of any size. In an ecosystem, there are biotic and abiotic components that are all linked. The pelagic zone or “open ocean zone”, where the giant tube worm, an underwater animal that lives near hydrothermal vents, lives is located next to the continental slope/drop off. The water is much deeper here. At the surface, there is

The topic I am writing about is the recent screwworm parasite outbreak in Florida. This is the first U.S. invasion of this lethal critter in thirty years. In at least two locations near the Florida Keys, samples confirm the screwworm invasion. The screwworm is deadly even though it looks like an ordinary fly. It feeds on living tissue and can “kill a fully grown steer in 10 days” (Guarino & Post, 2016). The only way these creatures can be killed off is with a fire that includes gamma radiation and X-rays. This creature can infect not only animals and humans, but also livestock. With the absence of the screwworms, it has saved the livestock industry over $900 million. These are a few reasons why this topic is worth considering. Many animal and

Unlike human saliva, this mucus does not contain digestive enzymes, and only purpose is to aid the process of swallowing. The food then progresses into the pharynx, where the gill clefts are located. The pharynx acts as a passageway between the mouth and the oesophagus. Constructed of two layers of non-striated muscle, the oesophagus carries the food through to the gizzard, making use of mucus cells which assist in this process. Digestion begins in the gizzard, as it is a muscular modification of the first section of the stomach. The gizzard grinds coarse foods into smaller pieces, and secretes digestive enzymes into the

Stem cell, being capable of giving rise to many other cells types, is one of the main developmental biology research methods in relation to flatworm regeneration. Major organisms, including flatworm taxa, are capable of showing little to no regeneration, leading to the observation of living species and how they interact to unravel the mechanism of regeneration, including aging. By utilizing the ability to observe BrdU labeling, used in cell proliferation, and maceration, the act of softening and breaking down skin due to moisture. Regeneration observed in living specimens showed to be a process that is completely successful when regeneration remained in the posterior-most pharynx level, otherwise failed if the animals lacked the brain & parts of the pharynx. Surprisingly, minimal cells are needed for a complete registration of the specimen, M. lignano that
