Correct Answer: Option 1 biodiversity

Biodiversity is the variety of life: the different plants, animals and micro-organisms, their genes and the ecosystems of which they are a part. Since there would be less variety of organisms left for propagation, the biodiversity in that area will not flourish. Plus, there would be fewer habitats left for survival so some of the organisms might migrate to places with more resources and better habitat.

Due to scarcity of resources brought about by the destruction of habitats, the organisms would tend to compete more on the few remaining food source. This would lead to more interaction between species. Thus, options 2 and 3 are incorrect.

As for option 4, sun could penetrate more through a clearing than densely covered area of habitat. Therefore, more solar radiation would reach the area.
