It seems like there's a bit of a misunderstanding in the question. Biologists are the ones who classify living things, not the other way around!

Here's a breakdown:

* Biologists: Scientists who study living organisms and their interactions with the environment. They are experts in classifying, identifying, and understanding the diversity of life on Earth.

* Classification: The process of grouping organisms based on their shared characteristics. This helps us organize and understand the relationships between different species.

So, biologists use their knowledge and skills to classify living things, not the other way around.
