Question

Identify the INCORRECT statement.

Options

• Around 25% of the drugs sold in the global medicine market worldwide are plant derivatives.

• 25,000 plant species are put to use by tribals worldwide as traditional medicines.

• The relationship between diversity and well being of ecosystem is linear.

• Rich diversity leads to lesser variation in biomass production over a period of time.

Answer 1

The relationship between diversity and well being of ecosystem is linear.

Explanation:

The relationship is not strictly linear. Research (notably by David Tilman) shows that ecosystem functioning is generally non-linear and that, up to a point, increasing diversity increases ecosystem functioning, then levels off.
