Many animals produce chemicals called pheromones, which send "smell-
messages" to other animals of the same species. These odors have different
meanings. One odor attracts a mate. Another sends a warning. Another
marks a territory. A honeybee, for example, makes over thirty-six different
pheromones to communicate such information
where to find good flowers.
An ant that has found food will take a bit of it and then head back "home"
to the anthill. As it carries the food, it wipes its stomach on the ground. This
leaves a chemical trail or path so that other ants will know where to go for
more food.
