You place equal numbers of dark and light varieties of feeder crickets into a terrarium containing a lizard. After two days, you notice that there are fewer light-colored crickets than dark-colored crickets. What process is taking place on a small scale within the terrarium? Design an experiment in which you could determine if color or taste is the primary factor responsible for the selective feeding of the lizard.

Selective Feeding

The process where organisms choose specific types of food over others based on nutritional needs, food availability, or other factors.

Terrarium

A sealed glass container containing soil and plants, and sometimes small animals, kept for observation or for decorative purposes.

Dark-Colored Crickets

Varieties of crickets that possess a darker pigmentation, potentially offering an advantage in certain environments.
