Question

which animals typically have a reproductive group and a nonreproductive group within their social structure?
bees
lions
moose
zebras

Explanation:

Eusocial animals have a strict social structure with reproductive and nonreproductive castes. Bees are eusocial: only the queen reproduces, while workers (female) and drones (male, limited role) make up nonreproductive groups. Lions, moose, and zebras do not have this fixed reproductive/nonreproductive group structure.

Answer:

bees
