(b) [1.5]
$\begin{array}{cc}\text{Genetic Biodiverstiy}& \text{Species Biodiversity}\\ \text{(a)Diversity within}& \text{Diversity at a species level.}\\ \text{a species over its}& \\ \text{distributional range.}& \\ \text{(b)It is trait of the species.}& \text{It is trait of the community.}\\ \text{(c)It influences adaptability}& \text{It influences biotic interactions}\\ \text{and distribution of species}& \text{and stability of the}\\ \text{found in an area.}& \text{community.}\end{array}$
