As we move from the equator towards the poles,species diversity $.........$.

The relation between species richness and area for a wide variety of taxa turns out to be a rectangular hyperbola. Give a brief explanation.

Approximately $25\%$ of all insects are known to be phytophagous (feeding on plant sap and other parts of plants).

The species-area relationship is a straight line described by the equation:

Which is not a reason for maximum diversity in the tropics?

Provide detailed information about the species-area relationship with the help of a graph. Explain the representation of the species-area relationship and how it becomes linear on a logarithmic scale.
