Explanation / Answer

8. Gene flow is affected by various factors which include geographical barriers, environmental factors and fitness of genes. In the given question Option A and B provide geographical area where movement of animals or plants would be easy whereas in the figure C movement would be difficult which will provide a challenge to gene flow. Hence most correct option would be Option C.

9. Habitat quality depends on various factors like size of population in the given area, diversity of species in the given area, and interspecific competition present in the area. Considering first two criteria that is size of population in the given area and diversity of species in the given area as constant, shape A will provide more equal space for species to get distributed and grow and thus shape A will have better quality of habitat as compared to shape B.

10. Legacy Effect is A legacy effect is defined as the the impact of previous conditions on the current ecological processes or properties. Thus considering the definition option B is the most correct option. It is past geological or ecological event that changed the heterogeneity of the landscape.

11. Biocentric Preservation was a motive for environmental preservation used by John Muir. It emphasize that all organisms has right to exist and follow their inetrest. Thus correct answer is option D, John Muir.
