Examples of Symbiosis

Predator/Prey- A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
Parasitism- Parasitism is a type of non mutual relationship between organisms of different species where one organism, the parasite(mosquito) , benefits at the expense of the other, the host(human). 

Mutualism- Mutualism is the way two organisms of different species biologically interact in a relationship in which each individual derives a fitness benefit (i.e., increased or improved reproductive output).
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).
