What do secondary and tertiary reproductives do in relation to colony formation?

The role of secondary and tertiary reproductives in relation to colony formation primarily involves migration to new colonies, enabling the growth and expansion of the species. These individuals are typically involved in the establishment of new colonies away from their original location, and they can do so without the need to emerge above ground. This behavior is crucial for the survival and dispersal of the colony, as it allows the insects to exploit new environments and resources while maintaining a degree of protection by remaining below ground.

In contrast, establishing new colonies requires adaptability and mobility, both of which are characteristics of secondary and tertiary reproductives. Their capability to venture out discretely ensures that they can find suitable locations for new colonies, thereby supporting the continuation and propagation of their genetic lineage.

The other choices reflect misunderstandings of the roles of these reproductives. For instance, the idea that they stay above ground to establish new colonies does not align with their typical behaviors. Furthermore, stating that they only assist primary reproductives or reproduce exclusively within the original colony limits their significant role in colony expansion. Rather, their primary function, as indicated, involves both migration and the potential for founding new colonies in new locations.
