उत्तर
The primary productivity in an ecosystem is expressed as gm-2 yr-1 or Kcal m-2 yr-1.
Explanation:
Primary production is defined as the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis. It is expressed in terms of weight (gm–2) or energy (kcal m–2). The rate of biomass production is called productivity. It is expressed in terms of gm–2 yr–1 or (kcal m–2) yr–1 to compare the productivity of different ecosystems.
