Task 4
Communal nutrition means that some members of a colony gather and provide different kinds of food to the entire colony. The professor uses ants as an example. Ants live in nests. The forager ants look for food every day. They don’t just bring back anything they find. When the colony is mostly of adult ants, they bring back sugar-rich items, like fruits. Because adult ants need energy to work. When baby ants are born, they need food that are rich in protein to grow into adult ants. So the forager ants will bring back food like certain types of leaves, or mushrooms, to provide enough protein for the baby ants to grow.
