What are some examples of mutualism commensalism and parasitism?

Mutualism Humans and Plants (We breathe out carbon dioxide then the plants absorb it then release oxygen.... etc. ) Humans and plants both benefit from this relationship Commensalism Killdeer Birds and Cape Buffalo (the Killdeer Bird lies down on the buffalo and the buffalo protects the Bird. But the bird DOES NOT harm the buffalo.) Birds benefit, but Cape Buffalo is not affected Parasitism Ticks and Humans (The ticks suck the blood and is therefore benefited, but does not benefit the human, but harms them instead. ) The ticks benefit, but humans are harmed.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
