Ecosystem Relationships

Filed under Physical Science

An ecosystem is made up of all the organisms in an area as well as their relationships with each other and with the nonliving materials in the environment.  Describe at least two ecosystem interactions that occur between organisms in an area.  For example, commensalism is a relationship in which one organism benefits and the other is neither benefited or harmed. You cannot use this type of ecosystem interaction.  You will have to research two other interactions and describe each on this blog.

    One example of an interaction is the food chain. the food chain is a chain of organisms of what they eat or who they are eaten by. An example of the food chain is algae -> krill -> fish -> seal -> whale. Another example is the habitat. This is because they can be destroyed and built.

    two ecosystem interactions that occur between organisms in an area are one when a predator benifitting off its prey by eating it, second when a tree takes nutrients from the soil so it can grow those are two interations between organisms in an area

    One type of ecosystem interaction is called mutualism. Mutualism is when two organisms interact. One benefits at the expense of another. Another type of ecosystem interaction is called parasitism. Parasitism is a relationship between two different species, one is the parasite, the other the host. In this relationship, the parasite benefits at the expense of the host.

    One example of parasitism is that if you get bit by a mosquito, you lose blood and the mosquito benefits from it. Another example is competition. For example, some male animals have to fight each other, and whoever wins the fight, gets to mate with the female.

    In this passage you will learn about two different types of ecosytem interactions. An ecosystem is the combination of physical and biological elements of any certin enviornment.
    The first ecosystem I will type about is mutualism. Mutualism is when two organisms benifit from each other. One exsample of this is called mutalistic, this is when a fungi grows on a pine tree. The fungi takes most of the sugars from the pine tree, without harming the tree. In return that helps the pine tree retain more water, so it can grow more.
    The second type of ecosystem is Parasitism. Parasitism is when the parasite, benifits from the host. The host in return is always killed. ( Such as moths, butterflies, and others.) The parasite decreases the host health. It also uses the host for food, that it eats. The parasite also ulters the host behaviour. An exsample of this is, when a tick ataches its self to a dog. The tick drinks the blood, and nutrients for the dog (host) and if the tick is not found, the dog will die.
    Now you know of two more ecosystems you probly didnt know before. They are mutalism and parasitism. In the end they either benfit each other, of harms one and the other benifits from it.

    Two ecosystem interactions that occur between organisms in an area would be Predation and Mutualism. Predation is where a predator feeds off of its prey. Mutualism where each individual derives a fitness benefit.

    O.k. for example a predator and a prey one feeds the other, one needs the other for food. And one species benefits the expense of the other which is similar to ecosystem and their relationships.

    One example of an interaction in an, well any, ecosystem would be the relationship of a predator and its prey. A predator, such as a fox, hunts its prey, rabbits or other small rodents, for food. And if that fox had pups not only would the parents benefit but so would the pups. And if the dead rabbit was not finished then scavengers would also feed, benefit, off that rabbit. So not only are predators and prey in that kind of relationship but any scavengers as well.

    Some lizards can adapted by changing their skin color to hid from other animals that want to eat them.Most lizards of all kind can do this color changing thing.

    Two different type of ecosystems are Symbiosis and Parasitism. Parasitism is when a parasite benifits at the expense of the host. And Symbiosis is where both organisms benifit from the relationship.

    An example of an interaction in any ecosystem is a predator and its prey. Or the food it eats. An example of a predator is the tiger. It runs around hunting for its food. This helps the cubs learn how to hunt for there prey. An example of the prey is a deer. The deer gets eaten by the tiger, so there is no benefit for the deer. Although there is a benefit for the tiger.

    There are many different kinds of ecosystem interactions. One example of an ecosystem interaction would be a scavenger because they feed off of animals that have already died. Another one could be a decomposer which is when an organism causes decay by consuming waste and dead bodies. If we did not have decomposers, every time an animal would die its body would just stay and lay there for a very, very long time.

    in any ecosystem, there is going to be the predator and the prey. For example, a big black bird searches fields for field mice. Eventually the bird will find the mouse and eat it. There is no benifit for the mouse, but there is for the bird. another example is, an oak tree and a pine tree. they don’t need each other to survive, so they benifit from a relationship.

    The first example is a preditor and it’s prey. A preditor can only survive by eating meat so that means it has to eat things that eat o the land or eat it’s own kind to survive.the second one is that plants grow of the land and the rain and the herbavors eat that to survive so the main purpose of the plant is to supply food to other creatures and other organisms

    Competition is an ecosystem relationship where the two organisms fight in order to survive or “survival of the fittest”. Another ecosystem relationship is a Predation, a kind of relationship where small organisms are hunted and eaten by bigger organisms like how cats eats mice.
