Question 1 · 1 mark · Difficulty 1/3

Which of the following best defines biodiversity?

  1. The number of different species in an ecosystem
  2. The variety of life in all its forms, including genetic diversity, species diversity and ecosystem diversity
  3. The total number of organisms living in a habitat
  4. The range of different habitats found in a country
Show answer & explanation
✓ Answer: B — The variety of life in all its forms, including genetic diversity, species diversity and ecosystem diversity
Award 1 mark for recognising that biodiversity includes all three levels: genetic diversity, species diversity and ecosystem diversity. A is incorrect because it only describes species diversity, not the complete definition. C is incorrect because it refers to population size, not diversity. D is incorrect because it focuses only on habitat variety, missing genetic and species components.
Question 2 · 1 mark · Difficulty 2/3

The table shows data on forest cover in a country over 30 years. Year | Forest cover (million hectares) | Number of endemic bird species recorded 1990 | 45.2 | 126 2000 | 38.7 | 118 2010 | 31.4 | 104 2020 | 28.9 | 97 Which statement best explains the relationship shown in the data?

  1. Forest cover has no effect on bird species diversity
  2. As forest cover decreases, the number of endemic bird species increases due to natural selection
  3. Reduced forest cover correlates with loss of endemic bird species, likely due to habitat loss
  4. Bird species cause deforestation by damaging trees
Show answer & explanation
✓ Answer: C — Reduced forest cover correlates with loss of endemic bird species, likely due to habitat loss
Award 1 mark for identifying the correlation and linking it to habitat loss. The data shows both forest cover and species numbers declining together, suggesting habitat loss reduces biodiversity. A is incorrect as the data clearly shows a relationship. B is incorrect because species numbers decrease, not increase. D is incorrect because birds do not cause deforestation; the relationship is reversed.

CIE IGCSE Biology: Conservation of biodiversity FAQ

How many CIE IGCSE Biology questions on Conservation of biodiversity are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Conservation of biodiversity for CIE IGCSE Biology, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CIE paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CIE IGCSE students preparing for Biology?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Conservation of biodiversity practice with other Biology topics or even switch to a totally different CIE subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Conservation of biodiversity questions aligned to the official CIE IGCSE Biology syllabus?
Every question is written against the published CIE IGCSE Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CIE.
How is Conservation of biodiversity typically tested on CIE IGCSE Biology papers?
Conservation of biodiversity appears across multiple question types on real CIE IGCSE Biology papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
