A founder population arrives on a new island, and multiple newer species diverge.

Explanation / Answer

Q 5)

Q 6)

TRUE

Ecological opportunity arises from two fundamental elements: (1) niche availability, the ability of a population with a phenotype previously absent from a community to persist within that community and (2) niche discordance, the diversifying selection generated by the adaptive mismatch between a population's niche-related traits and the newly encountered ecological conditions.
