Respuesta :
In the species equilibrium model, if the extinction rate increases, the number of species on an island should decrease.
The species equilibrium model describes the theoretical relationship between immigration and extinction of species to islands, depending on their size and distance from the mainland or other species source. The equilibrium model of island biogeography, from the question, states
that the species composition on an island will constitute a balance between the immigration and extinction rates. The succession on the island would be how the species composition on an island develops gradually with time.
So, species arriving later might outcompete
earlier arriving species. As the Islands
continue to develop, major players like the
primary producers and other factors that
aid ecological development would support
the growth of species that would previously
have struggled to live on the island.
