Question 1 · 1 mark · Difficulty 1/3

Which of the following is the main reason why tropical rainforests are deforested?

  1. To reduce flooding in low-lying river valleys
  2. To provide timber for building conservation centres
  3. To create land for agriculture and cattle ranching
  4. To allow native species to colonise new habitats
Show answer & explanation
✓ Answer: CTo create land for agriculture and cattle ranching
The primary driver of tropical deforestation is the conversion of forest land to agricultural land, including crop farming and cattle ranching. This destroys complex habitats that support thousands of species.
Question 2 · 1 mark · Difficulty 1/3

A river receives large amounts of nitrate fertiliser from nearby fields. What term describes the process where excess nutrients cause excessive algal growth, leading to oxygen depletion?

  1. Eutrophication
  2. Nitrification
  3. Decomposition
  4. Bioaccumulation
Show answer & explanation
✓ Answer: AEutrophication
Eutrophication is the process where excess nutrients (especially nitrates and phosphates) enter a water body and cause rapid, excessive growth of algae. This ultimately depletes oxygen levels and kills aquatic life. Bioaccumulation refers to the build-up of toxins in food chains.

AQA GCSE Biology: Biodiversity and the impact of human activities on ecosystems FAQ

Is Kramizo free for AQA GCSE 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 Biodiversity and the impact of human activities on ecosystems practice with other Biology topics or even switch to a totally different AQA 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 Biodiversity and the impact of human activities on ecosystems questions aligned to the official AQA GCSE Biology syllabus?
Every question is written against the published AQA GCSE Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA 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 AQA.
How is Biodiversity and the impact of human activities on ecosystems typically tested on AQA GCSE Biology papers?
Biodiversity and the impact of human activities on ecosystems appears across multiple question types on real AQA GCSE 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.
