Symbiotic Relationships

                  Many scientist discovered that organisms have relationships. For example scientist discovered Parasitism, Mutualism, and Commensalism. Parasitism is when one organism benefits and the other organism gets harmed. There are many types of parasitism, the biggest example of parasitism is when a dog gets fleas. The parasite are the fleas and the host or victim is the dog. The flea gets blood from its hosts the dog. There are many more for parasitism now lets go Mutualism. Mutualism is when both organisms benefit, any example people might know of is the crocodile letting his teeth cleaned by a Plover bird. They benefit because the Plover bid gets free food, and the crocodile get his teeth clean and infection free. Another example of mutualism we humans haven't thought or maybe is the dog and man relationship. How they benefit the dog gets shelter, food, water, etc. the man is protected by his loyal friend and has a friend to talk and play. The last one is Commensalism it is when one organism benefits and other doesn't benefit or gets harmed. One example is the shark and the Remora. The Remora gets food, protection, and a free ride but the shark gets nothing no benefits.
