A. Consumption efficiencies of herbivore is higher in ocean than grassland
B. In aquatic ecosystems, production efficiencies of herbivore are greater than carnivores
C. Assimilation efficiencies for carnivores are typically higher than those of herbivores
D. Assimilation efficiency depends on the quality of food eaten and the physiological efficiency of the consumer

#Unit 10. Ecological Principles
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?
