What are 2 organisms in the grasslands that illustrate commensalism?

Where can i find 2 organisms in the grasslands that illustrate commensalism?

• Answer:

  Remember that commensalism is taken from a latin phrase that means "sharing a table". Commensalism takes place when two organisms coexist in a state where one is benefited and the other is neither harmed nor benefited. In the grassland you could probably think of many examples of this. One type of commensalism is "inquilinism" where one organism uses the other for housing. In the grassland small, insect-eating birds live and set up nexts in the grass and therefore profit from the grass but do the grass no harm or benefit, thus this is commensalism.
