Question：Using points and examples from the lecture, describe two ways ants regulate humidity.
Ants nest underground where it is pretty dry and lacks moisture. In order to get water and survive underground, there are two ways ants adopt. The first is to transport water tablet into the nest. The work is pretty laboring and intensive, because every ant can transport one drop of water a single time, and they have to keep transporting till the nest is watery enough. The second way is smarter, to forage water with the help of water trap. For example, the ants will lay materials that naturally suck in water at the gate of the night, such as feather, and keep it there overnight. After that, they can collect fresh water out of the material.
