Task 3

Syonomone

In the field of chemical ecology, scientists study the interactions of organisms with their environment that are mediated by the chemicals they produce. Many organisms communicate via chemical signals. A syonomone is a chemical substance produced by an individual of one species that benefits both the producer and the recipient which is of a different species. This message-bearing substance evokes a behavioral response in individuals of the same or other species.
