are male bees, usually born late in the summer to perform their one function - to mate with new queen bees. The drones then die whilst the new pregnant queens hibernate through the winter. Echolocation is a method of perception used to find out information about the animals surroundings and finding prey. Echolocation is used by animals such as orca, and bats and is a system similar to submarine sonar. An orca produces series of very loud clicks and the signal ‘hits’ objects and bounces back. The orca’s brain processes the information and the orca can then ‘see’ the image. Orca use echolocation to find out about their surroundings, where prey are and where other members of their pod are. Emergents are the tallest trees in a tropical rainforest which ‘emerge’ from the canopy (the leaky roof of the forest). They can measure over 60m tall
