Beta diversity will be highest when: A. Abiotic conditions are uniform from patch to patch. B. Dispersal rates of species are high. C. There are similar species interactions from patch to patch. D. Abiotic conditions are highly variable between patches.

Biodiversity will be highest when: Dispersal rates of species are high.

Explanation:

Dispersal increases the chances of having biodiversity as it helps the spread of biodiversity across the globe
