How did adaptive radiation affect plants after they first moved to land?
a. they evolved the ability to photosynthesize.
b. they evolved into animal-like protists.
c. they evolved into the kingdom fungi.
d. they evolved to fill the niches found on land.

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.  

the answer is d.

just did it on apex

thinking it would be d not too sure but i think it's right
