Use insect-colony and foraging evidence to explain how division of labour, specialization and shared tasks improve protection or resource collection in IB Biology HL C4.1.9.
The pavement ant (Tetramorium caespitum) eats organic matter found within its territory. Individual ants leave their nest to forage for food. When they find a suitable source of food they return and communicate to other ants in the colony where the food can be found.
