The idiosyncratic hypothesis suggests that: Multiple Choice Ecosystem function decreases as the number of species decreases. Ecosystem function changes unpredictably as the number of species increases or decreases. Ecosystem function is independent of the number of species. Ecosystem function changes in a predictable, but non-linear manner with a change in species number. Ecosystem function decreases as the number of species increases.

Agene pool: a) is the collection of all the alleles found in a single species b) is the collection of all the alleles found in a single population c) is the collection of all the chromosomes found in a single population d) is the collection of genes in a species that allow the individuals to swim
