What is suggested as the best measure to report the density of a dense laboratory culture of bacteria in a petri dish?
Options
- ATotal number of bacteria
- BGenetic diversity of bacteria
- CBiomass of bacteria
- DPercent cover of bacteria
Correct answer
C. Biomass of bacteria
Step-by-step solution
Although total number is generally the most appropriate measure of population density, it is in some cases either meaningless or difficult to determine. In an area, if there are 200 carrot grass (Parthenium hysterophorus) plants but only a single huge banyan tree with a large canopy, stating that the population density of banyan is low relative to that of carrot grass amounts to underestimating the enormous role of the Banyan in that community. In such cases, the percent cover or biomass is a more meaningful measur
