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 fallowA- Difference in dissolved oxygen between light bottle and dark bottle yield NET primary productivityB- Difference in dissolved oxygen between light bottle and initial bottle yield NET primary productivityC- Difference in dissolved oxygen between light bottle and initial bottle yield Grass primary productivityD- Difference in dissolved oxygen between light bottle and dark bottle yield total oxygen produced by photosynthesisWhich above combination of statement are correct? -triyambak.org
