Introduction
30/04/2010 4. How do animals communicate? 1a.what is communication? Communication is behaviour that influences the actions of other individuals. 1b.what does communication consist of? -making sounds -giving signals (e.g. special 'dances' in honeybees) -releasing chemicals called pheromones into the environment 2. Explain how different types of dance communicate information about the distance and direction bees must fly to find flowers. -an eight figure dance tells the other bees the direction and how far the food is. -a round dance tells the other bees that food is close by. 3. What are pheromones? -Pheromones are chemicals secreted by some animals that cause specific reactions in other animals, it makes communication possible. -A chemical hormone released by an organism for communication in the same species e.g. to attract (mating). ...read more.

They are attracted by pheromone, substance secreted by queen. - After mating, drone dies, so queen flies away alone. On average, the queen mates approximately 8 to 9 times. 5. Describe different ways in which animals can communicate and give some examples of each. -sounds: Bees communicate with each other about food sources using dances. The sounds from the movement of the bees is picked up by the tiny hairs on the bee's head. -signals for example 'dances' e.g. in the case of honeybees: Honey bee workers perform a series of movements, often referred to as the "waggle dance," to teach other workers the location of food sources - The round dance, a series of narrow circular movements, alerts colony members to the presence of food within 50 meters of the hive. ...read more.
Conclusion
-chemicals (pheromones) e.g. Honeybees check bees returning to the hive by touching them with their antennae (feelers). If the bee is from another hive, they drive it away. Pheromones play a role in the defense of the hive as well. When a worker honey bee stings, it produces a pheromone that alerts her fellow workers to the threat. That's why a careless intruder may suffer numerous stings if a honey bee colony is disturbed. Pheromones produced by the queen control reproduction in the hive. She emits pheromones that keep female workers disinterested in mating, and also uses pheromones to encourage male drones to mate with her. The queen bee produces a unique odor that tells the community she is alive and well. When a beekeeper introduces a new queen to a colony, she must keep the queen in a separate cage within the hive for several days, to familiarize the bees with her smell. ?? ?? ?? ?? 1 ...read more.
