Blog #9 (Community Interaction)

Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism Give an example and a picture for each
Competition: contest between individuals, groups, animals, etc. for territory, a niche, or a location of resources.  Competition occurs naturally between living organisms which co-exist in the same environment.

Commensalism: a class of relationship between two organisms where one organism benefits but the other is neutral (there is no harm or benefit).
  
mutualism:is the way two organisms biologically interact where each individual derives a fitness benefit
predation:describes a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked)
parasitism: is a type of symbiotic relationship between organisms of different species where one organism, the parasite, benefits at the expense of the other, the host
