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

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.
