Parasitism





Parasitism is when one organism is living inside a nother but it is hurming it. It is bad because one of the organisims is good but the other is not benefiting from the other ither thount worring about. In this case the other organism is being harmed.




An example of parasitism is a dog and a tick because the dog is gettin harmed but the tick is having benefits. This can also ocurre with humand and some animald that go inside your skin and ley some eggs.



The parasite that is benefiting is called a parasite. The other organism that is being harmed is called the host. It is dangerous to be the host because somtimes you can die. The parasite is always going to be good because he is getting all the benefits from the host.

Commensalism




Commensalism is also a part of symbiosis. Commensalism is when one specie benefits from the other but the other doesn't harmed or helped. This is going to be good only for one of the organisms. This is most common on animal and on plants less but you can also see it a lot.



An example of commensalism are the barnicles in a whale because the barnicles benefit from the whale. They are having were to live, but the whale does not benefit eather get harmed. A nother example is a bird an a tree. The tree does not get harmed nither benefits but the bird benefit because he is having were to get food and to have shelter.



Commensalism is the second in the list of the better parts of symbiosis. The first one is mutualism because bothe benefit. The second is commensalism because onley one get benefit but the other is not harmed, and the last one is parasitism because one gets benefits and the other get harmed.

Mutualism



Mutualism is a part of symbiosis. Symbiosis is the relationship between two organisms. Mutualism is that is beneficial to both species because thy do not harm each other. Most mutualisms are good, and they can live apart.


Some mutualisms are so intimate that the species cannot live without each other because they need the other.Many mutualisms are great in their interaction because you can see how they interact between each other.


For example if a bat eats and distributes the seeds of a friut in the forest it is going to mutualism because boath benefit. The bat benefit because he is eatng and the friut benefit because then the friut is going to distribute in another place.

Project Introduction


My name is Claudia Bustamante. I am an student and for my computer class I have been asigned to get a topic to teach other persons in a blog. I choose a topic from science.

My topic is about the characteristics of living things. In this project I have been asigned to have a role. My role is to be a guide and teach all kind of turists. I work at EcoBlueSea. My goal is to be an expert about the three kinds of symbiotic relationship in all the parts of the world. My situation is that a group or guides hired me for working with them.

My product is going to be an exel presentation were I am going to show information and after we are going to show in the forests, oceans and rivers.
