Which of the following ecosystems would likely have the largest net primary productivity per hectare and why?
A. grassland, because of the small standing crop biomass that results from consumption by herbivores and rapid decomposition
B. tundra, because of the incredibly rapid period of growth during the summer season
C. open ocean, because of the total biomass of photosynthetic autotrophs
D. cave, due to the lack of photosynthetic autotrophs


Answer :

A GRASSLAND would likely have the largest net primary productivity per hectare. It is because of the small standing crop biomass that results from consumption by herbivores and rapid decomposition.

What is a grassland?

Grassland can be defined as a particular type of biome where the dominant vegetation is represented by grasses.

In a grassland, trees can be present, but they are not the dominant vegetation of this biome.  

There are different abiotic factors that prevent the establishment of taller trees in a grassland (e.g., the amount of rain precipitation).
