🎯 What it covers
- GCSE Biology: homeostasis & thermoregulation (ectotherms), adaptation, classification, nutrition.
- BTEC / T-Level Animal Management: husbandry, health, and the welfare needs (Animal Welfare Act 2006).
- Applying knowledge to an unfamiliar animal — a common exam skill.
🃏 Flashcards (tap to reveal)
Ectotherm or endotherm?Tap to reveal
AnswerEctotherm — it relies on external heat (basking) to control its body temperature.
Which animal group?Tap to reveal
AnswerReptile (a vertebrate) — dry, scaly skin; lays eggs.
Why is UVB light essential?Tap to reveal
AnswerIt lets the dragon make vitamin D3 to absorb calcium. Without it → metabolic bone disease.
How does diet change with age?Tap to reveal
AnswerJuveniles ~80% insects (protein for growth); adults ~80% plants.
Name a desert adaptation.Tap to reveal
AnswerBehavioural thermoregulation (basking/seeking shade); water-efficient physiology; camouflage colouring.
One welfare need (AWA 2006)?Tap to reveal
AnswerA suitable environment — correct heat, UVB and space — one of the five welfare needs.
📄 Exam-style questions
Explain how a bearded dragon controls its body temperature. 4 marks
Mark schemeIt is an ectotherm (1); it basks in a warm spot / moves to heat to raise its temperature (1); it moves to shade / the cool end to lower it (1); this is behavioural — it relies on the environment, not internal processes (1).
Explain why a lack of UVB light can cause metabolic bone disease. 2 marks
Mark schemeWithout UVB the dragon cannot make vitamin D3 (1); so it cannot absorb/use calcium, leading to weak bones (1).
A keeper feeds an adult bearded dragon only insects. Evaluate this diet. 3 marks
Mark schemeAdults should eat mostly plants (~80%) (1); too much insect protein / too little plant matter can cause health problems, e.g. obesity or organ strain (1); recommend mostly leafy greens and vegetables with some insects (1).
