Productivity is expressed in terms of ________.

gm^-2yr¹
gm²yr¹
gm^-2yr^-1
gm^-1yr^-1

hint Hint:

In ecology, productivity refers to the rate of formation of biomass in the ecosystem. It is measured as weight(e.g., g/m2/yr) or energy (e.g., kcal/m2/yr).

The correct answer is: gm^-2yr^-1

In ecology, productivity refers to the rate of formation of biomass in the ecosystem. It can also be referred to as the energy accumulated in plants by photosynthesis.

The rate of synthesis of energy-containing organic matter or biomass by any trophic level per unit area in unit time is described as its productivity.

It is measured as weight(e.g., g/m2/yr) or energy (e.g., kcal/m2/yr).
