question 78

Multiple Choice

Please use the following information to answer the question(s) below.
The tundra biome is rapidly changing as a result of global warming. Studying the energy budget of the tundra can help scientists to evaluate the magnitude of these changes. In a randomly selected square meter of tundra, the amount of plant biomass is 200 g. The amount of new plant biomass added in a year is 100 g. In the same square meter, the total biomass added in a year is 15 g. A grasshopper that eats 1 g of plant biomass is able to use 0.15 g of that biomass for growth. The grasshopper cannot assimilate 50% of the plant's biomass.
-What is the maximum biomass of grasshoppers that could be supported by this square meter of tundra (i.e., if grasshoppers ate all of the existing vegetation) ?

• A) 100 g
• B) 50 g
• C) 20 g
• D) 15 g
