What happens as nymphs mature in a Drywood termite colony?

As nymphs mature in a Drywood termite colony, they undergo a transformation into either soldiers or reproductives. This process is crucial for the growth and sustainability of the colony. Nymphs are immature termites that eventually assume specialized roles within the colony structure.

Once they reach a certain stage of development, nymphs can differentiate based on the needs of the colony and environmental conditions. Some nymphs may develop into soldier termites, which are responsible for defending the colony against threats. Others may mature into reproductives, which are crucial for the colony's expansion and reproduction. This ability to transition into different roles is a key aspect of the termite social structure, allowing for a flexible response to the colony's needs.

The other choices do not reflect the biological and social dynamics of Drywood termite colonies. They do not simply die off without changing roles, remain nymphs indefinitely, or get replaced by workers, as the colony's hierarchy and functionality are maintained by the successful maturation of nymphs into specialized castes.
