Classifications and Symbiotic Relationships.

This week I finished watching the documentaries. On the website I learned about all of the different skulls and what they ate . It was pretty interesting because some species ate fruits and nuts, while another ate meat. We also started learning about how species are catagorized. A man named Carolous Linnaeus camed up with this naming of species. He maned each species by two names. This system is called Binomial Nomenclature. for example, the scientific name for a human is called a homo sapien. His real name is Carl Linny. He changed it to its latin form just like he names species. We also learned about Symbiotic Relationships. There is parisitic which means that the host of the organism gets a negative effect and the other organism gets a posotive effect . For example, and mousquito gets blood from a host and the the host loses blood. Mutalistic is when the host gets a posotive effect and the organ ism gets a posotive effect. For example, an elefant can have birds on it that eat the bugs bothering the elephant. The bird gets to eat, and the elephant is free of flies.
