Answer:
The correct option is D.
Explanation:
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.
Answer:
provide energy, contribute to body structure, and/or regulate chemical processes in the body.
Yes. For photosynthesis to occur a chemical reaction has to take place using chloroplasts and sunlight and water, to result in the production of glucose,water and oxygen. If any of the reactants or products are removed, the reaction does not occur. Thus, yes we require chloroplasts to allow an organism to undergo photosynthesis.
