A conservation programme reintroduces wolves into a national park. The deer population subsequently decreases and the vegetation cover increases significantly. This is an example of:

Q: How do I try a free CIE Biology question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Biology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Biology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Biology questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Biology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A conservation programme reintroduces wolves into a national park. The deer population subsequently decreases and the vegetation cover increases significantly. This is an example of:

Accepted Answer

A trophic cascade resulting from the reintroduction of a predator — A trophic cascade occurs when the reintroduction of a predator (wolves) suppresses the prey population (deer), allowing vegetation to recover — an indirect effect passing through trophic levels. Eutrophication involves excess nutrients in water, not predator–prey dynamics. Monoculture describes single-crop farming, not natural vegetation recovery. Primary succession begins on bare, uncolonised land, not in an established park with existing soil and species.

Answer

Eutrophication caused by increased nitrogen from wolf activity

Answer

Primary succession beginning after a disturbance to the ecosystem

Answer

A trophic cascade resulting from the reintroduction of a predator

Answer

Monoculture developing because deer are removed from the ecosystem
