Which statement is true regarding the primary members of a Drywood termite colony?

In a Drywood termite colony, the structure differs significantly from that of other termite species. For Drywood termites, there is typically no distinct worker caste. Instead, the roles of workers, soldiers, and reproductives are somewhat less defined compared to other types of termites.

In Drywood termite colonies, the reproductive members consist of a king and a queen responsible for continuing the lineage, while the other members of the colony primarily assist in feeding and caring for the young. These non-reproductive members do not classify into a distinct worker caste as seen in other termite species where workers are the majority, performing specific tasks like feeding the colony and defending it.

This unique characteristic highlights how the Drywood termite colony is organized without a rigid division of labor, which distinguishes it from other termites, where workers or soldiers often dominate the population. Hence, the statement emphasizing the absence of a distinct worker caste accurately reflects the biological and social structure of Drywood termite colonies.
