Question 2 Medium
A bird migrates for the winter. What type of adaptation is this?
Show answer
Answer: behavioural
- Migration is an action.
- It is behavioural.
Question 3 Medium
A plant on a shaded forest floor grows slowly. Name the abiotic factor it is short of.
Show answer
Answer: light
- Photosynthesis needs light.
- The shade means less light intensity.
Question 4 Medium
A bear sleeps through the cold winter months. What type of adaptation is hibernation?
Show answer
Answer: behavioural
- Hibernation is something the bear does.
- So it is a behavioural adaptation.
Question 5 Hard

Show answer
Answer: extremophiles
- They are adapted to extremes.
- They are extremophiles.
Question 6 Hard
A camel produces very concentrated urine. What type of adaptation is this?
Show answer
Answer: functional
- It is a process inside the body.
- It is functional.
Question 7 Hard
In a predator and prey graph which population peaks later?
Show answer
Answer: predator
- Predators respond to the prey.
- So the predator peaks later.
