Q1. In recent year's phytoplankton have been investigated as a potential source of energy for humans. Researchers have therefore been interested in whether this organism can be 'farmed' to provide food or fuel. In terms of biomass, Gross Primary production (GPP) in phytoplankton living in the layer just below the surface of a typical ocean area is 4102 g m-2 yr-1. If you assume the energy value of phytoplankton is 6 kJ g-1, compute the GPP in terms of kJ m-2 yr-1. Show the working clearly.
Q2. Genetic diversity is necessary for natural selection to act, but natural selection can decrease or eliminate diversity. What procedure can restore genetic diversity to a population?
