Here's why:

* It contains carbon: Urea has a carbon atom in its molecular structure (CH₄N₂O). The presence of carbon is a key characteristic of organic compounds.

* It is produced by living organisms: Urea is a waste product of protein metabolism in animals, including humans.

While urea might seem inorganic because it's a byproduct of biological processes and contains nitrogen, its carbon content and biological origin firmly place it in the realm of organic compounds.
