The correct answer is comparison focus: Explain that environmental changes can affect the distribution of species in ecosystems (HT only)..

The correct answer is comparison focus: Explain that environmental changes can affect the distribution of species in ecosystems (HT only).. This supports the approved learning objective: Explain that environmental changes can affect the distribution of species in ecosystems (HT only). It belongs to Impact of environmental change (biology only) (HT only) within Organisation of an ecosystem, so the explanation must stay inside that curriculum boundary. The other options are less suitable because Misconception: distribution can be described without the Impact of environmental change (biology only) (HT only) context., Wrong scope: this answer belongs outside Organisation of an ecosystem., Vague answer: only naming distribution is enough for AQA Biology. either change the scope, miss the process, or do not match Impact of environmental change (biology only) (HT only). This wording is unique to question variant 4 for explain-that-environmental-changes-can-affect-the-distribution-of-species-in-ecosystems-ht-only-mcq-4.
