It is genetically inherited from the parents. It does not require learning.
1 of 12
Describe innate behaviour
It is rigid and inflexible. Unintelligent. Patterns of behaviour are stereotypical.
2 of 12
Define innate behaviour
Any animal response that occurs without the need for learning. It is inherited.
3 of 12
What are the advantages of innate behaviours?
Help to avoid predators, find a habitat and find food.
4 of 12
What organisms are innate behaviours most suitable for?
Organisms such as invertebrates with a short life span, who live a solitary life and do not take care of their offspring.
5 of 12
Explain reflexes
Escape reflex to avoid predators. Earthworms withdraw underground in response to vibrations on the ground. Involuntary responses.
6 of 12
Explain kineses
Orientation. Rate of movement increases in unfavourable conditions. Non-directional response - response in relation to stimulus, not direction.
7 of 12
Give an example of kinesis
Woodlice avoid predation by living in dark and damp conditions. If in bright/dry, will randomly and rapidly move to find suitable conditions. Physiological response.
8 of 12
Describe taxes
Directional, orientation response. Direction of movement described in relation to stimulus which triggers behavioural response.
9 of 12
Examples of behavioural responses
Positive phototaxis=towards, negative=away from a light stimulus. Positive chemotaxis=towards, negative=away from a specific chemical.
10 of 12
Define FAP
Fixed action patterns. Stimulus causes a response/FAP.
11 of 12
Give an example of complex innate behaviour
Waggle dance by worker honey bees. Used to communicate distance and direction of food source to other honey worker bees.
