A stable grassland ecosystem is studied. The grass produces biomass at a rate of 650 g m−2 year−1650\text{ g m}^{-2}\text{ year}^{-1}650 g m−2 year−1.
What is the approximate biomass of the grass that becomes biomass in primary consumers?
0.65 g m−2 year−10.65\text{ g m}^{-2}\text{ year}^{-1}0.65 g m−2 year−1
6.5 g m−2 year−16.5\text{ g m}^{-2}\text{ year}^{-1}6.5 g m−2 year−1
65 g m−2 year−165\text{ g m}^{-2}\text{ year}^{-1}65 g m−2 year−1
650 g m−2 year−1650\text{ g m}^{-2}\text{ year}^{-1}650 g m−2 year−1
