B1.4 Interdedpendence and
Adaptations
Animal adaptations
BTEOTSSSBAT know how
animals adapt to different
environments
Summary
Organisms are well adapted to survive in their
normal environment. Population size depends
on a variety of factors including competition,
predation, disease and human influences.
Changes in the environment may affect the
distribution and behaviour of organisms.
Key words
Adaptation
Arctic
Biomass
Camouflage
Competitor
Desert

Use three words to describe each of these
environments.
The Arctic:

3.
Survival
To survive, organisms require a supply of materials
from their surroundings and from the other living
organisms there.
Organisms live, grow and reproduce in places
where, and at times when, conditions are suitable.
To do this they need to adapt to their environment.

B1.4 animals adaptations

  • 2. Animal adaptations BTEOTSSSBAT know how animals adapt to different environments
  • 3. Summary Organisms are well adapted to survive in their normal environment. Population size depends on a variety of factors including competition, predation, disease and human influences. Changes in the environment may affect the distribution and behaviour of organisms.
  • 5. The desert: 1. 2. 3. Use three words to describe each of these environments. The Arctic: 1. 2. 3.
  • 6. Survival To survive, organisms require a supply of materials from their surroundings and from the other living organisms there. Organisms live, grow and reproduce in places where, and at times when, conditions are suitable. To do this they need to adapt to their environment.
  • 7. The organisms that are best adapted to make use of their resources in a habitat are more likely to survive and increase in numbers For example: • To be able to obtain a certain food better. • To make it more difficult for predators to catch them. • To survive in extreme climates, eg arctic or deserts.
  • 8. Adaptation Adaptation is a special feature or behaviour that makes an organism particularly suited to its habitat.
  • 9. What are a shark’s general adaptations to life in an aquatic environment? A Shark’s General Adaptations streamlined shape to reduce friction when moving through water gills have a large surface area so that oxygen can be extracted from the surrounding water fins provide stability, power and control
  • 10. What are a shark’s specific adaptations to life as an aquatic predator? highly sensitive sense of smell that can detect drops of blood from miles away lots of very sharp teeth that are constantly replaced silver colouring underneath acts as camouflage specialized sense organs can detect the sound, movement and electrical fields of other organisms A Shark’s Specific Adaptations
  • 11. Compare these two animals… Desert Fox Arctic Fox
  • 12. Adaptations • The two environments we saw before are harsh environments for animals to survive in so the animals have had to adapt to survive.
  • 13. Cold climates Temperatures: • arctic winter can dip to -51o C • warmest month is between 10o C and 0o C Often permanent snow and ice
  • 14. Animals in Cold Climates • Arctic animals must keep themselves warm to survive. • You loose body heat through your body surface, mainly your skin. • Arctic animals have developed many adaptations to help them survive…
  • 15. Look at the following… What do these animals have in common?
  • 16. Animals in Cold Climates Common features: • Thick oily fur coats • Layer of blubber under the skin • Colour – many change colour in the summer • Small ears • Large feet What about body shape?
  • 17. Body Shape - Have fat, round body shapes with short legs - Have small ears – why?
  • 18. Hot Desert Climates Temperatures • Can reach 45 – 50o C during the day • Can fall below 0o C at night Less than 25cm rain a year
  • 19. Animals in Dry Climates • Animals in dry climates have to keep themselves cool to survive. • They also have to cope with a lack of water. • This means they are unable to lose heat through sweating
  • 20. Look at the following… What do these animals have in common?
  • 21. Animals in Dry Climates Common features: • Large thin ears • Little body fat • Thin, silky fur • Long limbs to help spread heat • They also often only come out at night. Why? What about body shape?
  • 25. Surface Area to Volume Ratio These have the same volume: 4 units³ Surface area = 16 units² Surface area = 18 units²
  • 26. Surface Area to Volume Ratio • Animals loose heat from the body surfaces that are in contact with the surrounding air/water. • Reducing this contact surface reduces heat loss • Increasing the surface increases heat loss
  • 27. Compare these two animals… Desert Fox Arctic Fox Can you add any adaptations or reasons for the adaptation?
  • 29. Which of the birds, A, B, C or D, is best adapted for: 1.tearing flesh 2. finding insects in cracks in the ground 3. crushing fruit 4. sieving small animals from mud? A C B D
  • 30. Adaptation for survival Animals have adaptations that help them survive The echidna has pointed spines on its back.
  • 31. The brightly coloured poison dart frog has a toxic skin
  • 33. This is the caterpillar of the butterfly Blue Mormon, it’s very difficult for caterpillars to survive to become butterflies, given their susceptibility to predators. But this caterpillar in particular has developed different strategies to survive

Editor's Notes

  2. Photo credit: © 2006 Jupiterimages Corporation Teacher notes A shark’s teeth are not fixed to its jaw but embedded directly into the flesh. Its teeth are constantly replaced as they fall out or are broken, so that a shark may get through thousands of teeth during its lifetime. The lower teeth are mainly used for holding prey, while the upper teeth are used for cutting. The shark’s specialized sense organs include: lateral lines – a row of fluid-filled sensory canals along each side of the shark. These can detect movement and changes in pressure from about 100m away. ampullae of Lorenzini – small pits in the shark’s snout that detect tiny electrical fields, such as those associated with muscle contraction of prey. auditory system – can detect the sound created by injured prey from over 1 mile away.
  3. Teacher notes This true-or-false activity could be used as a plenary or revision exercise on adaptation, or at the start of the lesson to gauge students’ existing knowledge of the subject matter. Coloured traffic light cards (red = false, yellow = don’t know, green = true) could be used to make this a whole-class exercise.
