Ants release pheromones, which are detected as a smell to other ants, when they have found food. This lets the other ants know that they can return to the nest in order to feast. Once the food runs out, the ants release a separate pheromone that lets the ants know that the food is gone. What type of pheromone are they expressing AND where are they sensing these pheromones

Ants have a poisonous gland that mainly secretes formic acid.

Explanation:

This is how ants communicate; it is a signal to other ants to return to the nest. Ants also release a separate pheromone that has a different function from the above, ie, message to other ants that the food is gone. The omission of this pheromone also indicates the territory of this insect species.

Such pheromones are useful in mating rituals and affect only ants of the opposite sex. Iron pheromones are semiochemical substances that are excreted from an individual's body to influence the behavior of another receiving person. From all the above examples, it can be concluded that ants thus communicate and organize their community.
