Question 1 · 1 mark · Difficulty 1/3

Which of the following best describes the role of nitrogen-fixing bacteria in soil?

  1. They convert nitrates into nitrogen gas, reducing soil fertility
  2. They convert atmospheric nitrogen into ammonia, increasing soil fertility
  3. They break down proteins into amino acids for plant uptake
  4. They convert ammonia into nitrates for absorption by fungi
Show answer & explanation
✓ Answer: B — They convert atmospheric nitrogen into ammonia, increasing soil fertility
Nitrogen-fixing bacteria such as Rhizobium convert atmospheric nitrogen (N₂) into ammonia, which can then be used by plants to synthesise proteins. This process increases soil fertility by adding usable nitrogen compounds to the soil.
Question 2 · 1 mark · Difficulty 2/3

A farmer notices that crop yields have declined over several seasons despite adequate rainfall. Soil tests show very low nitrate levels. Which action would most directly address this problem?

  1. Spray the crops with a fungicide to prevent disease
  2. Add nitrogen-containing fertiliser to the soil
  3. Increase irrigation to improve water uptake by roots
  4. Plant the crops closer together to reduce competition
Show answer & explanation
✓ Answer: B — Add nitrogen-containing fertiliser to the soil
Low nitrate levels in soil limit the plant's ability to synthesise proteins and chlorophyll, reducing growth and yield. Adding nitrogen-containing fertiliser replenishes nitrates so plants can resume normal growth. Other options do not address the identified nutrient deficiency.

CIE IGCSE Biology: Food production FAQ

How many CIE IGCSE Biology questions on Food production are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Food production 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 Food production 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 Food production 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 Food production typically tested on CIE IGCSE Biology papers?
Food production 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.
