The sampling effect hypothesis is an explanation for why productivity increases when plant species diversity increases. Which of
these predictions follows from this hypothesis? a) Productivity should be highest in the tropics, where species diversity is highest. '
b) The more mutualists are present (e.g. beneficial fungi, nitrogen-fixing plants), the higher the biomass.
c) If a certain "big-producer" is present, then biomass in a plot is high. If the big producer is absent, biomass is low.
d) There should be a strong positive relationship between the number of functional groups in an experimental plot and biomass.
If a certain “big-producer” is present, then biomass in a plot is high. If the big producer is absent, biomass is low follows from this hypothesis. Productivity means the condition, position, or action of remaining capacity to produce, organize, intensify the plant species. Therefore the sampling effect hypothesis is an explanation for why productivity increases when plant species diversity increases. The above mentioned prediction follows hypothesis.
(The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.)
