commensalism:
Commensalism is a reason between organisms were one benefits from the other but the other organism is unaffected. Barnacles and whales. In this example, the barnacles are able to have a safe place and are able to stay there. The Whales is unaffected by this and does not really care, therefore, this relationship between the Barnacles and whales is considered a Commensalism relationship.
Mutualisum:
Example1:
The honeybee pollinates a flower while gathering nectar because Mutualism is between two species who both benefit from each other. The Honeybee pollinates the flower to help it survive and live and the flower gives the honeybee nectar for the hive.
Example 2:
Mutualism is between two species who both benefit from each other.
For example, the oxpecker and the zebra or rhino, the oxpecker, or the bird, lives on the other organism, or the zebra or rhino. This is a Mutualism relationship between these two organisms because the oxpecker eats ticks and other parasites that live on their skin and the zebra or rhino gives it a place to live and be safe.
parasitism:
Parasitism is a relationship between two organisms were one organism, or the parasite feeds at the cost of the other organism or host. Ticks and dogs, these are two things a pet owner dreds to see. The tick is considered the parasite because it can get on to a dog and carries diseases with it. One disease is called the Rocky Mountain spotted fever, this can be harmful to the dog and can have it become very ill.
