What affects the extinction rate according to MacArthur-Wilson theory?

“Size of island” for what affects the extinction rate according to macarthur-wilson theory. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. At equilibrium, species identities can continue to turn over even when richness is approximately stable. The model predicts a balance of rates, not an absence of colonization or extinction. The remaining alternatives—“Temperature”, “Predation rate”, “Evolution rate”—refer to different states, processes, or scales and therefore do not express the same causal re

Biogeography

Island biogeography is also referred to as:

“Equilibrium theory” for island biogeography is also referred to as. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Island biogeography explains species richness as a dynamic balance between immigration and extinction. Immigration generally declines as an island fills with species, whereas extinction rises as more species divide finite area and maintain smaller populations. The remaining alternatives—“Dispersal theory”, “Genetic drift theory”, “Habitat theory”—refer to different states, processes
