Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism

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

Commensalism- In 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.


Mutualism- In 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 Brood parasitism, on the egg.
