How is a parasitic relationship different from a mutual or commensalistic relationship?

Answer 1

A symbiotic relationship is a relationship in which the two things are mutually dependant on eachother. A parasitic relationship is a relationship in which one thing (usually smaller than the other) is mutually dependant on the other. But the parasite is doing this at the other things cost. For example: A coral reef and a type of coral called Zooxanthellae have a symbiotic relationship with eachother. One reason the Great Barrier Reef is dying is because of the bleaching (loss of colour, which is not good) of Zooxanthellae. There are many examples of parasites, such as mosquitoes. An excellent example of a parasite is the leech. When the come in contact with your skin, they start sucking the blood out of you. This is why some hospitals and clinics use them to suck out poison. But after the poison is gone they keep sucking, like they do normally, which can be harmful.

Answer 2

A parasitic relationship is one in which a parasite lives off of the host. The parasite benefits from the host and harms the host at the same time.

A mutual relationship is one in which both organisms benefit without harming the other. Commensalism is when one organism benefits without harming the other.

Answer 3

A parasitic relationship is when two animals or more are involved. One animal is called the parasite and harms the other animal which is called the host. (One animal benefites and the other is harmed)

A mutualistic is when one animal is helping another animal and they both are benefiting. (Both animals benefit.)

There is also a relationship called commenselism which is where one animal benefits and the other neither benefits nor is harmed.

Hope this helps!! :)

Answer 4

In a parasitic relationship, one organism benefits at the expense of the other, which is harmed. In a mutualistic relationship, both organisms benefit from the interaction. In a commensalistic relationship, one organism benefits while the other is neither helped nor harmed.
