Survival Strategies in Responding to Environmental Factors in Animal Behavior

Explore how moisture, pH, light, and temperature impact animal behavior for survival. Learn about woodlice, plant shoots, frogs, and rhythmic behaviors in birds, hedgehogs, and cockroaches. Understand the significance of these responses for adaptation.

Presentation Transcript

  1. Animal Survival Responding to the Environment

  2. G1: Give examples of environmental factors that affect behaviour • Moisture • pH • Light • Temperature

  3. C1: Explain the significance of responding to environmental stimuli SURVIVAL!!!!

  4. Woodlice • Found in damp, dark conditions • Why damp? • Prevents body from drying out • Why dark? • Less likely to be seen by predators SURVIVAL!!!!

  5. Plant Shoots • Will grow towards the light source • Why? • To improve the rate of photosynthesis SURVIVAL!!!!

  6. Frogs • Found in damp conditions • Why? • Water is required for external fertilisation • Frogs need moist skin for gas exchange SURVIVAL!!!!

  7. 10 minutes Choice Chamber Dark Light Dark Light • G2: Describe the response of an animal to change in one environmental factor. eg, Woodlice  Light/Dark Conditions

  8. Woodlice do not deliberately move to the dark side – when they are in bright light they move around more quickly and if they happen to move into the dark side they will slow down or stop. SURVIVAL!!!!

  9. G3: Describe examples of rhythmical behaviour and in each case, identify the external trigger stimulus. • C2: Explain the significance of rhythmical behaviour in named animals. • Rhythmical Behaviour = behaviour that is repeated at definite intervals (daily, tidal or annually) • External Trigger Stimulus = the environmental factor which causes the behaviour to start.

  10. Birds • Migrate to warmer climates (annual rhythm) • Trigger Stimulus = shorter day length • Reason = escape cold temperature and shortage of food during the winter SURVIVAL!!!!

  11. Hedgehogs • Hibernate through winter months (annual rhythm) • Trigger Stimulus = shorter day length • Reason = shortage of food during the winter SURVIVAL!!!!

  12. Cockroaches • More active at night (daily rhythm - circadian rhythm) • Trigger Stimulus = darkness • Reason = avoid predators by feeding at night SURVIVAL!!!!
