An ant is a small insect that belongs to the family Formicidae. They are known for their social behavior, living in large colonies or communities. Ants have a distinct body structure, typically consisting of three main parts: the head, thorax, and abdomen. They communicate and work together to find food, build nests, and care for their young. Ants are found almost everywhere on Earth, except in extreme environments like Antarctica. They play important roles in ecosystems, such as aerating soil and helping with seed dispersal. Some species, like the leafcutter ant, even cultivate fungi for food.
