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 their body. ("National Geographic Common,") This first segment is the one located closest to the clitellum, which is the thick ring like band that demonstrates a worm is mature in growth. These worms move by taking full advantage of their small …show more content…
By doing this, they later will dig their way back down into the ground and ultimately digest these nutrients back into the soil, but now closer to the roots of plants. Therefore, this mixes the nutrients throughout the soil. ("Science Fair Projects," ) These castings, which are worm feces, also play a large role in helping plant growth as well. Castings are more beneficial to plants, more so than chemical fertilizers. This is because that castings do not have to be broken down before they can be used by the plant, therefore they can be used directly once produced by the worm. Also, castings consist of different minerals that plants also need in order to grow as well as they help to lower the potential risks of diseases that can develop in the roots of plants, such as root rot. ( "Tasteful Garden, Worm," ) In addition, castings cause the soil to clump together. These clumps then act as storage unit systems for water, which can later then be accessed and put into use by the plant. ("How earthworms can," ) However, these ways are not the only ways Earthworms tend to assist the growth in …show more content…
These tunnels help to ventilate the soil which plants need. Also, these tunnels allow the soil, and the plant, to take in more water. ("Science Fair Projects," ) Soil erosion too is regulated and kept to a minimum thanks to earthworms. Their tunnels allow for a place for the water to go. This is especially important in certain scenarios. For example, if you were to have plants in a pot of soil, the earthworm's tunnels would be what would help to ensure your soil remains in the pot and does not slowly erode away. ("eHow Do Earthworms," ) These things about earthworms are true and helpful for any plant, such as tomato
Sabellaria cementarium belongs to the phylum Annelids and is an invertebrate polychaete species. They are found in small clumps at the rocky bottoms of the sea floor where they use the rich source of natural phytoplankton as their primary diet (Qian and Chia, 1990). The tube-like worms can behave social and form extensive reefs or independently build hollow tubes in to the sandstone (pawlik and Chia, 1991). Embryos form a polar lobe that is absorbed in to the blastomeres at the end of division. Larval development and movement follows shortly after the 14-15 hour fertilization period where spiral cleaving of the fertilized oocytes appears (Render, 1983). Much is still not known about the invertebrate worm in their natural niche.
Oftentimes, people can recall at least one song they know that is undoubtedly catchy because of its repetitive nature. That song can become a nuisance, when it will not leave your mind. When a melody gets stuck in your head, sometimes it could take a whole day to forget the tune. A certain tune can be stuck in your brain for many years! In Oliver Sacks’ passage, “Brainworms, Sticky Music, and Catchy Tunes”, he talks about “earworms”, or a pathological repetition. Sacks uses patterns of development to inform the modern reader about the dark side of music.
The everyday death of man is a show for the angels. Our hero worm represents death and people are the actors. The worm of death is from the Phylum Nematoda. Many roundworms cause diseases in humans, which can lead to death. I have, however, reason to believe this is actually the blood fluke, Schistosoma of the Class Trematoda in Phylum Platyhelminthes.
Flatworms belong to the phylum Platyhelminthes. They have the simplest body plan of all bilaterally symmetrical animals. They are called flatworms because their bodies are compressed. The mouth is the only opening into the digestive cavity the flatworms have. Food is taken in through this hole and wastes are discharged also through this hole. Flatworms have a well-defined nervous, muscular, excretory, and reproductive system. The flatworm distributes the food it digests through a digestive tube that branches throughout all of its body parts. The fact that the worm’s body is flat serves many purposes. It allows the worm to hid in small spaces, to fit into the opening of other animals if the worm is parasitic, and it means that all the cells are close enough to the surface for exchange of oxygen and carbon dioxide with the environment (Meinkoth 399).
During the planaria experiment my intentions for my flat worm was to cut it in-between the eyes to give it two heads. Before making the dissection the first thing that had to be done was to feed the planaria, so it had the energy to regenerate.
Planarians are free living flatworms that are members of the class Turbellaria and phylum Platyhelminthes. Most are seen in fresh water environments, while others are found in large mosses, on land, and even in salt water. They are soft bodied, leaf-shaped, and ciliated animals that have two eyes, and a pointed tail. They have a mouth on the ventral side of their body often located half way to their tail. They typically grow between three and fifteen millimeters in length, and are a gray, brown, or black color. Planarians move by swimming, and some are relatively fast. Majority of planarians are carnivorous and feed on things like protozoans, small snails, and worms. All planarians are hermaphrodites, meaning that they contain
This disgusting worm parasite is spread by flies and mosquitoes. The adult worm spreads its larvae throughout the host’s lymphatic system and causes the lymph nodes to become clogged up. This also makes the tissue in the host’s body to swell up and create massive muscle deformations, otherwise known as elephantiasis. The elephantiasis mainly affects the legs and genitals. The disease also affects the eyes but that can be easily detected through close inspection but it commonly causes river blindness in the host. It’s been estimated that the parasite is one of the leading causes of blindness throughout the world.
You most likely think that worms are incapable of ingesting harsh materials, such as whale bone. To the surprise of many, zombie worms live at the bottom of the sea, living
A. “Humans are hosts to nearly 300 species of parasitic worms and over 70 species
Mao Dun, author of "Spring Silkworms", was a twentieth century Chinese novelist, critic, organizer, editor, and advocate for Chinese Communism. According to David Wang, Mao Dun was one of the most versatile Chinese literati among the May Fourth generation. Mao Dun was an advocate and practitioner of European naturalism. Motivated by history and politics, Mao Dun has introduced western literary ideas to China in his novels. As a left wing writer Mao Dun focuses on the peasant's point of view and relies on his depiction of reality to evoke change. A good example of this style of writing is the story "Spring Silkworms".
Edgar Allan Poe’s “The Conqueror Worm” represents a gothic view of death through the praise and genocide of society. Poe introduces the poem with the use of romance, which only expands the horror of the poem. The poem describes a play called “Man,” representing society where the audience is the angels. ‘The Conqueror Worm’ then appears, killing the patrons but is still praised as a hero. The final applause for the worm then suggests that he has helped society end its tragedy. “The Conqueror Worm” is a gothic genre due to its romantic, mysteriously dark and genius, oppressive atmosphere as well as creating a sense of death.
What is Vermicomposting Vermicomposting is worm composting, it’s a great way to recycle your carrot peelings, eggshells, coffee grinds, and used paper towels. Red wiggler worms can eat their body weight in food each day. As they eat, the worms create castings that are nutrient-rich organic matter. When castings mix with decomposed organic matter, you wind up with compost full of beneficial microbes and nutrients that, when spread in a garden, help feed, nourish, and protect growing plants. According to a 1998 article in Bio-resource Technology, vermicompost is compared with high-grade horticultural compost "has desirable aesthetics, has reduced levels of contaminants and tends to hold more nutrients over a longer period, without impacting the environment.
Compost is an easy solution to eliminating the waste that our environment brings, while at the same time, providing many benefits to us, and the environment. By using compost, it improves our plant growth by enriching the soil that it drinks its nutrients from. It helps us avoid buying soil amendments such as peat, bark mulch and bagged manure. Compost also loosens the heavy clay that is in our soil, while improving the capacity to hold water and adding essential nutrients.
...d female reproductive organs. An egg becomes fertilized when they rub clitellum. Earthworms play an important part in the environment. They break down organic matter and dig tunnels under the soil that help increase water and oxygen flow.
When studying plant nutrition, it is important to analyze the sources of the nutrition. Plants absorb their nutrients using their roots in the soil, however soil is not a uniform nutritive source. The plant’s wellbeing depends greatly on the quality, composition, and thickness of the soil. To help categorize such a broad topic, scientists have implemented a naming scheme for the different levels of soil. The first layer is closest to ...
