Question 6 • CMS 2026-2027 Biology CREDIT RECOVERY

Which statements describe the relationship between the area and the biodiversity of an ecosystem? Choose two correct answers.

Answer
A
A half acre of rainforest would likely have greater biodiversity than a full acre of desert.
B
A large area of a forest will likely have higher biodiversity than a smaller area of the same forest.
C
Small ecosystems always have low biodiversity.
D
Large ecosystems always have higher biodiversity than smaller ecosystems.
E
The same area of two different types of ecosystems will have the same biodiversity.

Explanation

A larger area of the same ecosystem can support more habitats and resources, so it will likely contain more species; this makes B correct. Ecosystem type also matters: rainforests generally support much greater biodiversity than deserts, so even half an acre of rainforest would likely have greater biodiversity than a full acre of desert, making A correct. The words “always” in C and D make those claims too absolute.
