Which caste of termites is responsible for gathering food?

The workers are the caste of termites that are responsible for gathering food. This caste plays a crucial role in the colony's survival by foraging for cellulose, which is the primary food source for termites, derived from wood, plant material, and other organic matter. Workers are also responsible for feeding the soldiers and the reproductive members (both primary and secondary reproductives) of the colony, as well as caring for the young.

The other castes do not fulfill this role. Soldiers are primarily tasked with defending the colony against threats, particularly from predators. Primary reproductives focus on reproduction to ensure the growth of the colony, while secondary reproductives also contribute to the reproductive function but are usually present when the primary reproductives are unavailable or need support. Therefore, the gathering of food and providing sustenance is a specific function that is distinctly assigned to the worker termites, making them vital to the colony's health and functionality.
