Basic
What are the 2 types of adaptation?
Structural and Behavioural
Name 2 ways in which animals adapted for protection.
Outer covering (shells), Camouflage, Mimicry, Warning colours, Living in groups and Distractions
Name 2 ways that living things breathe.
Lungs, breathing tubes, breathing holes, water bubble, gills, moist skin
How do we know the diet of the organism by looking at their skull?
Sharp teeth > Meat
Flat Molar > Plants
Both > both
What do birds normally do when it is nearer to winter?
Migration
Name 2 reasons why adaptation is important for animals to adapt to the surrounding?
To cope with physical factors of the environment (eg. Lack of water, extreme climate), To reproduce, To escape from predators, To hunt/forage for food.
What is the difference between camouflage and mimicry?
Camouflage: To blend in with the surrounding to avoid detection
Mimicry: Look like other animals to scare its predators
What do ducks have that help to move on water?
Webbed feet
Name a way that animals use to help them hunt for food.
Use of vemon, Traps, Light
Name 2 structural adaptations that cacti have to survive in the desert.
Needle-like leaves to reduce water loss
Thick stem to store water
Shallow and widespread roots to absorb rainwater
What is the difference between structural and behavioural adaptation?
Structural: Physical characteristics of the animal
Behavioural: Actions taken by the animal
Animals like the poison dart frogs and coral snakes are brightly coloured. Is this adaptation harming to them? Explain.
No. They are poisonous and it warns their predators that wanting to eat them is a bad idea.
What is stored in the gill chambers that allows animals like crabs and mudskipper to survive on land for a short period of time?
Water
Pitcher plant depends on insects for food. Do you agree? Explain.
No. Being a plant, it can photosynthesise for food.
(Depends on insects for more nutrients as they grow in nutrient-poor soil)
Polar bears have stiff hair on their paws. What is the purpose of this?
It is to increase the friction between their paws and the ice, allowing the bears to walk on ice easily.
Living in groups is a form of protection. How does it work? (2 ways)
Predators will have a harder time to reach the weaker animal in the group.
The animals can also run away is different directions to confuse the predator.
Name 3 factors that enable a bird to fly
Hollow bones, Strong flight muscles, streamlined body shape, feathers to keep the wings warm and well-developed wings
Name 2 structural adaptations that birds of prey have to hunt for food.
Sharp beak, Sharp talons, Keen eyes
Although arctic fox and fennec fox are both foxes, the size of their ears is very different. Describe their ears and explain why there is such a difference.
Arctic fox > Small ears. Smaller surface area to reduce heat loss to the cold surrounding
Fennec fox > Big ears. Bigger surface area to increase heat loss to the hot surrounding
