What is an interaction? describe an example and identify the variables within your population (work, social, academic, etc.) for which you might expect interactions?

An interaction is the action that occurs in 2 people while having any kind of conversation. For example, I am interacting with you by telling an answer. A population interaction example is, a dog and a flea. The flea jumps in the dog and drinks its blood. The dog scratches itself. This is an example of parasitism where one is benefited and other is harmed.
