To attract smaller animals as food.

To scare away larger predators.

3.
How does the professor clarify the concept of counter-illumination?

By describing its chemical formula.

What can be inferred about the 'burglar alarm' effect?

It is a completely safe defensive strategy for the prey.

It only works against predators that are smaller than the prey.
