Answer 1

Chemicals that are released by individuals and serve to influence the behaviour of other members of their own species are called pheromones.

Explanation:

Pheromones are chemical compounds that act as signals to communicate messages such as territorial boundaries, danger signals, caste regulation, and mating readiness, thereby coordinating social and reproductive behaviors within a species. For example, sex pheromones in some animals attract mates during the breeding season. This chemical communication plays a crucial role in the social organization and survival of many animal species, including insects and mammals.
