Animal Adaptations Quiz

Answer

An animal's ability to change colour instantly

Zebra (black and white stripes)

Answer

Arctic hare (white fur)

Answer

Stick insect (looks like a twig)

Answer

Leaf-tailed gecko (looks like bark)

Question 3

What is 'mimicry' as an animal adaptation?

Accepted Answer

When a harmless animal copies the appearance of a dangerous animal to fool predators

Answer

When an animal copies sounds from its environment

Answer

When an animal changes colour to match its background

Answer

When young animals copy their parents' behaviour

Question 4

Which adaptation does the Arctic hare use in winter to avoid predators?

Accepted Answer

Its fur turns white to match the snow

Answer

It burrows underground to hide

Answer

It migrates south to escape predators

Answer

It hibernates and avoids predators by sleeping

Question 5

What is hibernation and which animals use it as an adaptation?

Accepted Answer

A deep winter sleep where metabolism slows dramatically to survive food scarcity — used by bears, hedgehogs, and dormice

Answer

A daily rest period taken during the hottest part of the day

Answer

A long migration to warmer climates during winter

Answer

A period of reduced activity only lasting a few days

Question 6

The giraffe's long neck is a classic example of adaptation. What does it help the giraffe do?

Accepted Answer

All of the above

Answer

Reach leaves in tall trees that other animals cannot access, giving them an exclusive food source

Answer

Spot predators from a greater distance

Answer

Reach water without kneeling dangerously

Question 7

What is 'aposematism' in animal adaptation?

Accepted Answer

Warning colouration — bright colours that signal to predators that an animal is toxic or dangerous

Answer

The ability to produce and use venom

Answer

The ability to inflate the body to appear larger

Answer

A defensive spray used to deter attackers

Question 8

The Arctic fox has very small ears compared to its desert-dwelling relative, the fennec fox. Why?

Accepted Answer

Small ears lose less heat — large ears would be a disadvantage in extreme cold

Answer

Arctic foxes hunt by sound less than fennec foxes

Answer

Arctic foxes evolved from a different ancestor than fennec foxes

Answer

Small ears provide better camouflage in snow

Question 9

What is 'convergent evolution' and give an example?

Accepted Answer

When unrelated species independently evolve similar adaptations to similar environments or challenges

Answer

When two species evolve away from each other

Answer

When one species gradually becomes another species

Answer

When two related species diverge into different forms

Question 10

The woodpecker has several adaptations for hammering wood. Which of these is NOT a real woodpecker adaptation?

Accepted Answer

A beak lined with rubber-like material to absorb impact

Answer

A shock-absorbing skull with thick spongy bone

Answer

A very long, barbed, sticky tongue that wraps around the brain for storage

Answer

Strong feet with two toes forward and two backward for gripping tree trunks

Question 11

What adaptation do animals like sharks, tuna, and dolphins share that makes them fast swimmers?

Accepted Answer

Fusiform (torpedo) body shape that minimises water resistance

Answer

Identical shaped tails

Answer

Countershading colouration — dark on top, light below

Answer

All three adaptations together

Question 12

Why do some deep-sea fish produce their own light (bioluminescence)?

Accepted Answer

To attract prey, communicate with mates, or confuse predators in the pitch-black deep ocean

Answer

To warm the cold water around them

Answer

To photosynthesize like plants

Answer

To scare off large predators with a blinding flash

Question 13

The bombardier beetle has one of the most remarkable chemical defences in the animal kingdom. What does it do?

Accepted Answer

It mixes two chemicals in its abdomen that react explosively, firing a boiling toxic spray at predators with a loud bang

Answer

It sprays cyanide gas

Answer

It releases an extremely sticky glue that seals a predator's mouth shut

Answer

It electrocutes predators with a generated electrical charge

Question 14

What is 'countershading' in fish and marine animals?

Accepted Answer

Being dark on top and lighter below, making the animal harder to see from above and below

Answer

Changing colour to match colourful coral backgrounds

Answer

Having identical patterns on both sides of the body

Answer

Producing bioluminescence to counter darkness

Question 15

Some animals practise 'thanatosis' as a defence mechanism. What is it?

Accepted Answer

Playing dead — becoming completely limp and motionless to deter predators

Answer

Secreting toxic chemicals through the skin

Answer

Shedding a body part to escape

Answer

Making themselves appear much larger

Question 16

The electric eel generates electricity. What adaptations make this possible?

Accepted Answer

Special cells in its skin called electrocytes that act like biological batteries, stacked in columns

Answer

Copper-based blood that conducts electricity

Answer

A specialised organ that absorbs static electricity from the water

Answer

Small crystals in its scales that generate piezoelectric charges

Question 17

What is 'autotomy' and which animals use it as a defence?

Accepted Answer

The ability to voluntarily shed a body part — like a tail — to escape a predator, which then regrows

Answer

The ability to change colour automatically in response to background

Answer

The ability to produce toxic chemicals automatically when touched

Answer

The ability to automatically camouflage without conscious control

Question 18

Migration is a behavioural adaptation. What triggers the migration of wildebeest across the Serengeti?

Accepted Answer

The smell of rain and the resulting fresh grass growth

Answer

The movement of rival herds they must follow

Answer

Magnetic navigation from birth location

Answer

The rising of a specific constellation in the night sky

Question 19

Which adaptation allows the migratory monarch butterfly to travel 5,000 km from Canada to Mexico?

Accepted Answer

Both B and C — monarchs use both sun compass and magnetic navigation

Answer

Exceptional flying speed that allows rapid travel

Answer

Sun compass navigation combined with a time-compensated internal clock, using the sun's position to navigate

Answer

Magnetic sense that detects Earth's magnetic field

Question 20

What is 'thermoregulation' and how do different animals achieve it?

Accepted Answer

Controlling body temperature — endotherms (warm-blooded) generate internal heat; ectotherms (cold-blooded) rely on external heat sources

Answer

The ability to change body colour to regulate temperature

Answer

The ability to survive in both hot and cold environments without any special adaptations

Answer

A process by which animals lower their core temperature in summer
