One of the roles of ecological succession is to allow species with different adaptations to interact. Ecological succession occurs in stages, providing periods of what A overlap only for species that migrate. B separation only for species that do not migrate. C separation for all species. D overlap for a variety of species.

D overlap for a variety of species.

Explanation:

During ecological succession, a sequence of changes occurs in a community at a temporal and spatial level. Local colonizations and extinctions occur while ecosystems evolve at a more complex level.  

Ecological succession occurs in stages. The first stages are represented by communities of simple trophic levels and few species. With time, as the communities go through different stages, they transform into more complex ecosystems, that are much richer in diversity, and showing more interaction among the different species that compose it.  The final stage is known as the climax and represents a mature and stable system.

While the community is going through these changes, many species get extinct while many others get to emerge and survive. It occurs overlapping of different taxonomic groups that interact with each other competing or beneficiating other groups.
