In ecology, _________ is determined by dividing the biomass per unit area by the age of the forest ecosystem.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. biomass productivity.
In ecology, the term you're referring to is "Net Primary Productivity (NPP)." NPP is determined by dividing the biomass (total mass of living organisms) per unit area by the age of the forest ecosystem. This metric helps quantify the amount of energy that plants in an ecosystem capture and convert into organic matter through photosynthesis, minus the energy lost through respiration.
