Which level of biodiversity represents different ecosystems like deserts, rainforests, etc.?

Answer and explanation

Correct answer: Ecological diversity

Direct answer: B, ecological diversity. Biodiversity can be understood at several levels. Genetic diversity means variation in genes among individuals of the same species, such as different varieties of rice. Species diversity means the variety and relative abundance of species in an area. Ecological diversity means the variety of ecosystems, habitats and ecological processes in a region. Deserts, rainforests, grasslands, wetlands and mangroves are different ecosystems, so the example clearly points to ecological diversity. A is wrong because it deals with different species, not whole ecosystems. C is wrong because it deals with differences within one species. D is not the standard level used for this classification and is less precise than ecological diversity. Memory cue: genes = within a species, species = among species, ecosystems = ecological diversity.
