Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism Give an example and a picture for each

Competition:
In ecology, the interaction between two or more organisms, or groups of organisms, that use a common resource in short supply. 







Sea Anenomes compete for the territory in tide pools


CommensalismIn ecology, commensalism is a class of relationship between two organisms where one organism benefits but the other is neutral (there is no harm or benefit).




Barnacles attaching to scallops, not harming them. 


Mutualism- Mutualism is the way two organisms biologically interact where each individual derives a fitness benefit




A hummingbird benefitting from a flower, however the flower also benefits from it by getting pollinated.


MutualismIn ecology, predation describes a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked).







Praying mantis eating a bee. 


Parasitism- A type of symbiotic relationship between organisms of different species where one organism, the parasite, benefits at the expense of the other, the host.
