Ants are tiny but wise. Scientists have discovered that ants work together like a super-organism(超个体)to solve difficult problems.
Communicating with Chemicals. Ants can't talk, but they use special smells to “speak”. When an ant finds food, it leaves a smell path. Other ants follow this path to find the food. Scientists call these smells pheromones(信息素).
Jobs in the Colony(群体). In an ant family, every ant has work. Young ants clean the nest and feed babies. Older ants go out to find food. If too many ants get hurt, the healthy ones quickly take over their jobs.
Saving the Group. Fire ants show incredible courage during floods. They link their legs and heads to form a floating boat, keeping the queen and babies safe in the centre. Some ants at the bottom of the boat are washed away, but their death saves the group. This behaviour inspires engineers to build robots that work together during disasters like earthquakes.
Learning from Ants. Scientists now copy ants' ways to improve human life. For example, computer programs based on ant behaviour help trucks find the fastest delivery routes. In farms, people study how ants protect crops from pests naturally.
Who knew such small creatures could teach us so much about working together and being creative? The next time you see an ant, remember—it's part of a powerful team that achieves big things!
