chemical signals
Biochemical communication method
Chemical signals are molecules released by one cell or organism that trigger a response in another.
In biology, they include hormones traveling through the bloodstream, neurotransmitters crossing synapses, and pheromones communicating between individuals of the same species.
Ants follow chemical signals to find food sources.
The term appears in contexts ranging from cellular biology to animal behavior.
