Relationships with Organisms

Relationships With Organisms

Today as well as many years ago, relationships have happened with organisms. Organisms have three relationships which consist of mutualism, parasitism, and commensalism. These relationships happen at every part of the world.

First, mutualism is where both organisms benefit from each other. Think of a oxpecker on top of a zebra; the oxpecker eats all the ticks and fly on top of the zebra while the zebra is termite free. Another example is a spider crab and algae. The crab is able to blend in due to the algae on top of the crab. On the other hand, the algae is able to live on a good place while not being eaten from other organisms. Both organisms benefitting has helped them to be able to exist today.

Next, parasitism is where one organism benefits and the other is harmed. This type of relationship has caused organisms to become extinct in today’s world. One example of this relationship is a tape worm and a cow. The tape worm connects itself to the cow’s intestine, injuring the cow but giving food to the tapeworm. Another example can be fleas and dogs. The fleas bite and attack the dog’s skin creating red spots on top of the skin. The dog then feels itchy and is very annoyed. As you can tell, problems towards organisms have happened due to parasitism.

Finally, commensalism is where one organism benefits, and nothing happens to the other organism. A big whale is swimming through the ocean, and you see these little circular white things connected to it. These white things are called barnacles and they benefit from the whale because, as the whale is swimming, food swims by and the barnacles are able to get them. The whale, though, feels nothing. It’s just like a remora and a shark. The remora is able to stay safe due to the shark it is connected to. The shark, on the other hand, feels the fish but is not harmed.

Years have passed and today we still have three relationships between organisms. They consist of mutualism, parasitism, and commensalism. All of these help to benefit one or more organisms in the process of these.
