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 – (instinctive) = not modified by experience. Is genetically
determined.
• Learnt – behaviour that changes as a result of experience. Is flexible.

PLANT RESPONSES
• Plants have a large surface area compared with their volume in order to
absorb minerals and CO2.
PLANT RESPONSES
• Plants have a large surface area compared with their volume in order to
absorb minerals and CO2.
• 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 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.

- Fundamental niche = a niche that would be occupied if all the necessary
environmental conditions were present. Limits are set by physiological
tolerances – abiotic factors.
