What is behaviour? Behaviour is the way in which an organism acts in response to a stimulus.Behaviour helps an animal to survive. For example, a zebra will run away if it sees a lion. The stimulus is the sight of the predator, and the behaviour is running. This behaviour helps the zebra avoid being caught and eaten.
Types of stimulus Animals respond to both internal and external stimuli. An external stimulus is a change in the animal’s environment. For example the sound of a predator may be heard. An internal stimulus is a change inside the body of an animal. For example, an animal may feel thirst.
What is innate behaviour? Innate behaviour is pre-programmed behaviour in animals. Animals carry out this behaviour instinctively, without the need to learn new skills. For example, web building is innate behaviour for spiders. Spiders are able to produce the same web pattern each time with little variation. This behaviour is not taught.
What is learned behaviour? Learned behaviour is when an animal develops behaviour through experience. Learning helps animals acquire new skills for survival. For example, over time a monkey will learn the best way to open nut shells. Experience and repetition can also improve existing behaviour in animals.
What is a reflex response? Areflex response is an automaticresponse to a stimulus. These responses happen instantly, helping the animal react to danger quickly. For example if a snail is disturbed it will retract all of its soft body into its shell. This reflex response helps to protect the snail from predators. Reflexes are usually innate, however they can be learned.
What is imprinting? Imprinting is a special form of behaviour in which an animal learns to recognize an individual as it’s mother. This occurs early in an animal’s development. Some newly hatched birds imprint on the first thing they see. They will then stay close to the individual and accept food from them.
What is social behaviour? Social behaviour is any interaction between animals. Each type of social behaviour helps the species survive and reproduce. • Courtship behaviour, allows animals to recognise one another as members of the same species, and may lead to mating. • Cooperative behaviour, involves two or more animals working together to help the group. • Territorial behaviour, helps animals to defend their territory against other individuals. This can decrease competition for resources.
What is courtship behaviour? Courtship behaviour is a ritual that helps animals to confirm that they are of the same species but opposite sex, allowing them to mate. This is often a series of actions, like a sound, dance or a display, that shows the animal’s fitness as a potential mate. In many species the female will select the male that displays the most impressive courtship behaviour.
Investigating innate behaviour Herring gulls are large, noisy birds that live in the UK. These birds lay their eggs in a nest. When the chicks hatch they are fed with food regurgitated by the adults. The sight of the parent’s beak acts as a stimulus which causes chicks to respond by pecking at the beak. This behaviour will cause the adult herring gull to regurgitate food. What is it about the beak that acts as a stimulus for the chicks?
Investigating behaviour Woodlice have several behavioural adaptations that help them to survive and reproduce. They are land-dwelling invertebrates that have a shell-like exoskeleton around their body. If they detect a threat they roll themselves up into a ball, so they are surrounded by exoskeleton. For this reason they are often called pill bugs. Do you know what sort of places woodlice like to live in?
water Woodlice experiment Using a choice chamber you can investigate how the woodlice respond to different conditions. A choice chamber is a box that helps to create different types of environment. The woodlice can move freely between the chambers. water-absorbing material
