Question

A temperature grassland biome has a gross primary productivity of 3,480 kcal/meter^2/year and a net primary productivity of 2,000 kcal/meter^2/year. Which of the following is the approximate number of kcal/meter^2/year available to herbivores in that biome?

A. 1,000 kcal/meter^2/year
B. 1,480 kcal/meter^2/year
C. 2,000 kcal/meter^2/year
D. 3,480 kcal/meter^2/year

Answer 1

The approximate number of kcal/meter^2/year available to herbivores in a temperature grassland biome is 1,480 kcal/meter^2/year.

Step-by-step explanation:

The approximate number of kcal/meter^2/year available to herbivores in a temperature grassland biome can be calculated by subtracting the net primary productivity from the gross primary productivity. In this case, the approximate number of kcal/meter^2/year available to herbivores would be 1,480 kcal/meter^2/year (3,480 - 2,000 = 1,480).
