* Life Science: Entomology focuses on the study of insects, which are living organisms. It investigates their biology, behavior, ecology, and interactions with the environment.

* Zoology: Entomology falls under zoology, the study of animals. It delves into the specific aspects of insects, a diverse and fascinating group within the animal kingdom.

While entomology might touch upon aspects of earth science (like how insects interact with their environment) or physical science (like insect biomechanics), its core focus is on the biology and life processes of insects, firmly placing it within life science.
