1. Ants will approach biscuits and smell and taste them with their sensory organs, trying to evaluate the nutritional value and safety of biscuits.

2. If the ant judges that the biscuit is safe, it will start to use the special structure of its mouth and legs to carry the biscuit and bring it back to the ant nest for the ant colony to share.

3. The ant will also leave pheromones on the road so that other ants can follow its path to find cookies.
