일개미, or worker ants, are the non-reproductive female ants in a colony. They are responsible for various tasks, including foraging for food, caring for the queen's offspring, and maintaining the nest. Worker ants are typically smaller than the queen and male ants, and they possess strong mandibles for carrying and manipulating objects. These ants communicate with each other using pheromones, which are chemical signals that convey information about food sources or threats. 일개미 play a crucial role in the ecosystem by aerating the soil and helping to decompose organic matter, contributing to nutrient cycling in their environment.
