Show Answers:

  1. What are the different types of innate behaviours?
    • Rhythmic behaviours: behaviours that repeat at regular intervals
    • Social interactions: communication behaviours, reproductive behaviours, dominance hierarchies, territoriality
  2. What are different types of rhythmic behaviours?
    • Feeding behaviour: Individually, as a group
    • Migration: the movement of large numbers of animals over a long distance from one area to another area and their subsequent return to their original home.
    • Sleep: Nocturnal, diurnal
  3. What components are involved with communication between animals and what are the different types?
    • Stimulus, sender, receiver, kind of signal, how it is sent, behaviour of the receiver and setting in which the behaviour occurs
    • Sounds, visual display, touch, posture, and chemical signals (pheromones)
  4. Define social interactions
    It involves two or more individuals and may involve cooperation as in mating or ensuring food source. It can also involve aggression and conflict eg. selecting a mate or for territories
  5. Define the different types of learnt behaviour
    • Classical conditioning: is when a neutral stimuli is repeatedly associated with a second stimuli that elicits a reflexive response. Eventually the organism associates the first stimuli with the reflexive response
    • Operant conditioning: the actions of the organism depends on the types of consequence (positive or negative)
    • Insight learning: the ability to apply past experience to solving a new problem
    • Imprinting: the formation of an attachment to something in the environment
    • Habituation: the ability to 'get used to' a repeated stimulus
  6. What is tropism?
    The growth of a plant in response to a stimulus such as light or water
  7. What is phototropism and the role of auxin?
    • When a plant moves in response to light
    • If light is concentrated on one side, auxin moves away from the light source to the darker side. The increase in concentration of auxin causes that side to grow faster compared to the side exposed to the sun making it lean towards the light
  8. What is geotropism?
    • When plants respond to gravity. 
    • Gravity causes auxin to accumulate on the lower side of the plant causing one side to grow faster than the other and eventually making the distribution even by pointing straight up
  9. What is thigmotropism?
    A change in growth in response to contact with another object
  10. What are nastic movements?
    Independent of the direction of the stimulus including
