According to scientists' research, ants lack sugar in caves, which is very unfavorable for their growth and development. In order to find enough sugar, once ants find something sweet, their tentacles will harden spontaneously, which is a nature of ants. Not only ants, but also many animals like sweet things, such as humans. It may be that ancient ancestors found that sweet plants generally did not contain toxins, so they chose sweet things as food. In later evolution, taste became more sensitive to sweetness. Some plants enhance the sweetness of fruits or stems to attract animals in order to meet the needs of reproduction and spread.

Different ants eat different foods. Harvest ants eat seeds. They collect seeds in the cellar. Leaf-cutting ants eat mushroom slices. They take the leaves underground to cultivate mushroom slices. Some ants store insects called aphids. They extracted a sugary substance from aphids as food, which is very similar to the way humans milk cows.
