ANIMAL BEHAVIOUR

ANIMAL BEHAVIOUR • Complicated = animal’s response to environmental factors may be determined by the animal’s internal environment. -

ANIMAL BEHAVIOUR • Complicated = animal’s response to environmental factors may be determined by the animal’s internal environment. - Eg – male magpies attack in the breeding season but not at other times.

INNATE AND LEARNED BEHAVIOURS • Innate – (instinctive) = not modified by experience. Is genetically determined.

INNATE AND LEARNED BEHAVIOURS • Innate – (instinctive) = not modified by experience. Is genetically determined. • Learnt – behaviour that changes as a result of experience. Is flexible. • https: //www. youtube. com/watch? v=Eyy. Dq 19 Mi 3 A •

PLANT RESPONSES • Plants have a large surface area compared with their volume in order to absorb minerals and CO 2.

PLANT RESPONSES • Plants have a large surface area compared with their volume in order to absorb minerals and CO 2. • They achieve this by having a finely divided body shape which prevents them moving from place to place.

PLANT RESPONSES • Plants have a large surface area compared with their volume in order to absorb minerals and CO 2. • They achieve this by having a finely divided body shape which prevents them moving from place to place. • Plant movement can be in two ways: - Growth response = slow, permanent changes in cell size

PLANT RESPONSES • Plants have a large surface area compared with their volume in order to absorb minerals and CO 2. • They achieve this by having a finely divided body shape which prevents them moving from place to place. • Plant movement can be in two ways: - Growth response = slow, permanent changes in cell size - Turgor responses = reversible and due to changes in cell water content (eg. Stomata closing, or venus fly trap shutting)

ADAPTATIONS • Structural – aspects of the body (eg. Tail of a monkey)

ADAPTATIONS • Structural – aspects of the body (eg. Tail of a monkey) • Behavioural – behaviour. (eg. Finding shade)

ADAPTATIONS • Structural – aspects of the body (eg. Tail of a monkey) • Behavioural – behaviour. (eg. Finding shade) • Physiological – chemical process of the body (eg. Poison in snake fangs)

ECOLOGICAL NICHE • The way an organism has adapted in response to the habitat it lives in.

ECOLOGICAL NICHE • The way an organism has adapted in response to the habitat it lives in. • Combo of where it lives, how it lives there, and the role the organism performs in the community it is a member of.

ECOLOGICAL NICHE • The way an organism has adapted in response to the habitat it lives in. • Combo of where it lives, how it lives there, and the role the organism performs in the community it is a member of. - Fundamental niche = a niche that would be occupied if all the necessary environmental conditions were present. Limits are set by physiological tolerances – abiotic factors.

Limits are set by physiological tolerances – abiotic factors. - Realised niche = the actual niche that it occupies. Set by biotic factors.
