Verified step by step guidance1
Understand the historical context: Aristotle was one of the earliest naturalists who attempted to classify organisms based on their observable characteristics.
Recognize that Aristotle divided organisms into two main groups: plants and animals. This classification was based on their ability to move and their mode of nutrition.
Learn that plants were considered stationary and autotrophic (producing their own food), while animals were mobile and heterotrophic (relying on other organisms for food).
Note that Aristotle's classification system was very basic and did not account for microorganisms or other forms of life that were unknown at the time.
Conclude that the correct answer to the question is 2, as Aristotle divided all organisms into two groups: plants and animals.
