Unit 8.1 - Responses to the Environment

Visual Signals - Bright colors, Body movements

Best in light or open environments (e.g., birds flashing feathers).

Auditory Signals - Sounds and calls

Useful over long distances or at night (e.g., wolves howling).

Chemical Signals - Pheromones

Common in mating or marking territory (e.g., ants leaving scent trails).

Tactile Signals - Touch

Often seen in bonding or care (e.g., grooming in primates).

Electrical Signals - Electric fields

The main function of communication is to send and receive information, which helps with finding mates, avoiding predators, defending territory, and coordinating with others.
