A chimpanzee using a long twig to catch termites is an example of a(n)?

This is a classic example of tool use.

Here's why:

* Tool: The chimpanzee is using an object (the twig) that is not part of its body to achieve a goal (catching termites).

* Goal-directed: The chimpanzee is not simply playing with the twig, but is intentionally using it to access food.

While it's not considered true "culture" in the human sense, this behavior highlights the cognitive abilities of chimpanzees and their capacity for problem-solving.
