Answer: Adaptive radiation refers to the ability of living organisms to evolve rapidly from an ancestral forms into variety of other forms especially when the organisms move into a new environment that has abundant resources. The resources, which are present abundantly in the environment allow the living organisms to spread out in the environment and to find different habitats in the environments that favour their survival.In the question given above, adaptive radiation allows plants to fill different habitats (niches) that are found on land and to spread out rapidly.
