Year 9 Science Ecology Symbiosis Symbiosis Symbiosis is the relationship between two living organisms. The main types of symbiosis are mutualism, parasitism and commensalism. The association between the two organisms can be beneficial to one or two of the species or in some cases be harmful, depending on the type of symbiosis. Commensalism Commensalism is a biological term which is used to describe the relationship between two living organism, where in which one benefits from the other without harming it. Commensal species benefits from its hosts by obtaining food, shelter, transportation and other support. The host species is rarely ever harmed by the Commensal species. The term commensalism was founded in 1876 by Belgian Paleontologist and Zoologist Pierre-Joseph Van Brenden. Commensalisms comes from the latin word “commensalis” which translates to “sharing a table”. Commensal Relationship …show more content…
An example of two animals in a Commensal relationships is the remora fish and shark. The remora fish being the commensal species attaches itself to its hosts belly using a special sucker disk in its mouth. It travels alongside the shark and uses it for transportation. The remora fish consumes the parasites which buildup on its host body and benefits its by keeping the shark clean. The remora fish also eats any leftover food which was previously consumed by the shark. In short the remora fish benefits from its host by means of food whereas the host benefits by keeping clean and free from
The host's response to infection is inflammation. An interaction between parasite and host, whereby the relationship is beneficial for the former but detrimental to the latter, is characterized as parasitism.
An example of a commensalism relationship is the relationship between the Red Squirrels and the Red Oak Tree. The scientific names are the Sciurus Vulgaris and Quercus Rubra. The tree provides food and protection for the squirrel, but the squirrel does not harm or help the tree. The predator-prey relationship is when one organism, the predator, eats another organism, the prey. One example is between the Bobcat and the White-tailed Deer.
2.What part of the article most highlights the connection between loneliness and the potential effect that has on the basis of social behavior, specifically bullying? In your answer make sure to briefly explain the connection. Within the article “The Evolutionary power of Loneliness”, by Emily Singer, the collection of multiple experiments connect the idea that the negative effects of loneliness drive animals to interact with each other, however, this interaction can translate into competitive nature. One of the experiments mentioned in the article describes a trial between the interaction of mice.
Introduction: The article "How Kitty is Killing the Dolphins" by Christopher Solomon discusses how pathogens from land are travelling into the oceans and affecting marine environment such as, otters, dolphins, and orca whales. Solomon mentions how human and animal feces are one of the ways causing marine wildlife to fall ill of viruses and diseases. The article explains many pathogens and how they are harming the animals and also ways to prevent the furthering of the pathogens.
And they are the mascot of the UAPS. The Blobfish is important because without them the crustacean population could overpopulate, messing up the food chain. Pollution affects them because trash floats in their environment and ruins their habitat. They also eat the garbage that floats down to the bottom, poisons them, then kills them.
They also develop and reproduce quickly, making them ideal for testing the health of an aquatic ecosystem. They rely on the sugars that they obtain from
Introduction: Antagonistic behaviors are those conflict behaviors that include aggressive and submissive behaviors. Antagonistic behaviors tend to occur over territoriality. Every animal is looking for the most advantageous place to live and this results in having conflicts with other animals similar to their species and their needs. Animals fight for territory for many reason including: competition for food, to avoid interruptions while mating, survival and others. Fighting becomes a result from intrusion.
It is asserted that this increase in the number of salmon is due to a bottom-up effect, which increases resources salmon need, benefitting the species and allowing a population increase. An increase in water temperature has been shown to increase zooplankton populations, and this gives salmon fry a higher rate of survival. As temperatures have increased, salmon also develop faster and stay sheltered longer, evading predators more. When the water is at a cooler temperature, there are less zooplankton, slower fry development, and an increased vulnerability to predators. This observed increase in pink salmon populations has lead this species to have a top-down effect on other salmon species.
A Study Case of Amazonian Calf Interactions Introduction The Amazonian manatee is a very well known and loved species of manatee. Out of all of the Manatee species the Amazonian manatee is the smallest that utilizes only fresh water habitats. It has a fairly limited habitat that falls in the Amazonian Basin 's rives and lakes.
The relationship instead of being recognized as a form of a symbiotic relationship, lets say predation, they don't know the term itself, but they recognize the two species in the sort of relationship as “natural enemies.” Most humans are scared of lions, tigers, and bears, but lack the knowledge of much about those animals. This is largely sue to the fact that they do not understand how metaphors influence how the public interprets these creatures. They yes are deadly to their prey, but they are not our “natural enemy,” they are in fact beautiful creatures that deserve respect and protection from those that wish to harm them from their misconceptions from the well know phrases like: “lions, tigers and bears! Oh
The mutualism mentioned can be observed in the relationship between Cinderella and her animal friends. In the first part of the movie, the mice and the birds are shown to help Cinderella prepare her clothes as well as the things she needed while bathing. The group of mice and birds also help Cinderella in preparing her dress for the ball at the palace. Cinderella, in return to her friends’ help, has given the mice and the birds clothes, food, and most especially, kindness. It is clearly seen that in exchange of the service she received from her ‘friends’, she give them what they needed.
INTRODUCTION This course requires an examination of the addicted person in terms of the systems that they interact with. Through the use of the Ecological Systems Theory, an examination will be made of the facets and factors that affect various systems depicted in the film Traffic (2000). For the purpose of this paper a short review of the movie will be depicted.
When anyone says the word ‘relationship’ the first thing that pops into everyone’s head is boyfriend, girlfriend or marriage, but there are many different kinds and forms of relationships. For example, relationships can be with friends, teachers, coworkers, ect., and there are different forms of relationships aswell like, mutualism, which is a relationship where all the organsims benefit, or parasitism, which is a relationship where one partner benefits and the other is harmed. In the short novella Of Mice and Men by John Steinbeck and in the novel Tuesdays with Morrie by Mitch Albom the reader sees the common theme of relationships,whether they be good or bad. In the short novella Of Mice and Men Steinbeck shows many positive relationships, an example of a positive relationship would be the two main characters George and Lennie.
Urie Bronfenbrenner was a Russian born American, he was born on 29 April 1917 and died on 25 September 2005. Urie was a developmental psychologist and was very well known for his ecological systems theory on child’s development. This theory basically states that there are different levels that influence a child’s development. Each level of this system has its own advantages and disadvantages and each level is of the same importance as the other.
