Symbiosis

This past week in science we were learning about symbiosis. Symbiosis is a close relationship between two organisms in which one organism lives near, on, or even inside another organism and which at least one organism benefits. There are three different types of symbiosis. There is commensalism, parasitism, and mutualism. Commensalism is a form of symbiosis when one organism benefits and the other is not harmed. Parasitism is a form of symbiosis in which one organism benefits and the other is harmed. Mutualism is a form of symbiosis in which both organisms benefit. An example of commensalism is moss and a tree. An example of parasitism is a flea and a dog. An example of mutualism is a honey bee and a flower.
