What are three reasons scien-
tists have for classifying
organisms?

Classification, Interactions w/ other organisms, Similarities between other organisms

Explanation:

Three simple reasons to why scientists classify organisms is that they do so scientists can classify what type of organism one is so living things can be grouped or classified into one of the 7 Kingdoms. Scientists also classify organisms to see the relation between the organism and other organisms. They do so to possibly study relationships like mutualism, commensalism, predation, parasitism, and competition. This also leads to the third reason that scientists can see the similarities of the classified organisms by comparing it with other organisms of the same of opposite group.
