Answer :

The communication of animals using sounds and visual cues (such as color changes, expressions, or body movements) is referred to as an open system. Here's why: 1. **Open system**: Animals use various forms of communication to interact with each other and their environment. This open system allows for flexibility and adaptation in their communication methods, enabling them to convey information effectively. 2. **Examples**: - **Sounds**: Animals like birds use different calls to warn about predators or to attract mates. - **Visual cues**: Chameleons change color to communicate their mood or to blend in with their surroundings. - **Body movements**: Bees perform intricate dances to communicate the location of food sources to other bees in the hive. In summary, the diverse ways animals communicate through sounds and visual cues constitute an open system, enabling them to express a wide range of messages and behaviors in their natural environment.
