Measurement of phytoplankton production, take sample of phytoplankton suspended in three bottles in lake. One bottle as control assumed as initial, second bottle (D) was kept in dark while third bottle (L) was kept in light. After some time productivity measure fallow
A- Difference in dissolved oxygen between light bottle and dark bottle yield NET primary productivity
B- Difference in dissolved oxygen between light bottle and initial bottle yield NET primary productivity
C- Difference in dissolved oxygen between light bottle and initial bottle yield Grass primary productivity
D- Difference in dissolved oxygen between light bottle and dark bottle yield total oxygen produced by photosynthesis
Which above combination of statement are correct?
