Question
Compare and contrast innate behaviour and learned behaviour.
Markscheme
a. behaviour is observable impulse/reaction of an organism to «internal and external» stimuli
b. exhibited behaviour results from the combination of inherited traits, experience and environment
OR
exhibited behaviour is a result of the combination of innate and learned behaviour
Award [5 max] if no similarities are given.

-
20N.3.HL.TZ0.8b:
Explain how natural selection can cause mate selection behaviour patterns to develop in a species such as eastern bluebirds.
- 20N.3.HL.TZ0.8c: Another type of behaviour is altruistic behaviour. Outline an example of altruistic behaviour.
- 17N.3.HL.TZ0.06a: State the effect of simulated ship noise on foraging behaviour.
-
17M.3.HL.TZ2.7b:
Suggest reasons for the length you stated in (a) being the most common length of M. edulis that C. maenas eat.
- 17M.3.HL.TZ2.7a: State the most common length of M. edulis eaten by the C. maenas population.
-
18M.3.HL.TZ1.7c:
Distinguish between innate behaviour and learned behaviour in the development of birdsong.
- 19N.3.HL.TZ0.7a: Courtship behaviour leads to mate selection. Describe innate behaviour.
-
20N.3.HL.TZ0.8a:
Evaluate the hypothesis that females prefer to mate with males whose feathers are a brighter blue.
- 19N.3.HL.TZ0.7b: Explain the implications of courtship behaviour in natural selection.
-
19M.3.HL.TZ2.6a.i:
Suggest a reason for the plateau in the graph when only one crab is present in the cage.
- 19M.3.HL.TZ2.6b: Outline the role of natural selection in animal behaviour.
-
19M.3.HL.TZ2.6a.ii:
Determine whether foraging by crabs is dependent on number of prey (mussels) or number of predators (crabs).
-
17N.3.HL.TZ0.06b:
Predict the consequences on C. maenas of increasing noise related to human activity.
-
18M.3.HL.TZ1.7d:
Outline an example of a change in animal behaviour as a result of natural selection.
-
18N.3.HL.TZ0.7:
The drawing shows male and female Emperor birds of paradise (Paradisaea guilielmi ) found in Papua New Guinea.
Suggest how the external features and courtship behaviour of these birds of paradise affect reproductive success.
