Back to Basics- Symbiosis
Symbiosis is a big word! Edmond thought he would teach you how to pronounce it before we explained more about it.
Symbiosis: interaction between two different organisms living in close physical association, typically to the advantage of both.
-Mutualism: symbiosis that is beneficial to both organisms involved. (Ex- anemones and clownfish)
-Commensalism: a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter. (Ex- yellow tangs and sea turtle)
-Parasitism: relationship in which one organism (the parasite) benefits and the other (the host) is generally harmed. Parasites derive nutrition from their host and may also gain other benefits such as shelter and a habitat in which to grow and reproduce. (Ex- barnacles)
Now you know all about symbiosis, including how to pronounce it!
