## Net Biomass Solution

STEP 0: Pre-Calculation Summary
Formula Used
Net Biomass = Gross Primary Production-Gross Decrease in Biomass
Nbiomass = Ibiomass-Dbiomass
This formula uses 3 Variables
Variables Used
Net Biomass - (Measured in Biomass Kilogram per Square Meter) - Net biomass is the amount of biomass left after the substraction of the decrease of biomass from the increase of biomass.
Gross Primary Production - (Measured in Biomass Kilogram per Square Meter) - Gross Primary production is the biomass produced by organisms over a period of time.
Gross Decrease in Biomass - (Measured in Biomass Kilogram per Square Meter) - Gross Decrease in Biomass is the loss moving upward the ecological pyramid as only 10% energy is transmitted to the next level.
STEP 1: Convert Input(s) to Base Unit
Gross Primary Production: 100 Biomass Kilogram per Square Meter --> 100 Biomass Kilogram per Square Meter No Conversion Required
Gross Decrease in Biomass: 16 Biomass Kilogram per Square Meter --> 16 Biomass Kilogram per Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Nbiomass = Ibiomass-Dbiomass --> 100-16
Evaluating ... ...
Nbiomass = 84
STEP 3: Convert Result to Output's Unit
84 Biomass Kilogram per Square Meter --> No Conversion Required
84 Biomass Kilogram per Square Meter <-- Net Biomass

## What is Ecoforestry?

Ecoforestry has been defined as selection forestry or restoration forestry. The main idea of ecoforestry is to maintain or restore the forest to standards where the forest may still be harvested for products on a sustainable basis. Ecoforestry is forestry that emphasizes holistic practices which strive to protect and restore ecosystems rather than maximize economic productivity.

## How to Calculate Net Biomass?

Net Biomass calculator uses Net Biomass = Gross Primary Production-Gross Decrease in Biomass to calculate the Net Biomass, The Net Biomass formula is defined as the amount of biomass left in the universe after the elevation of trophic level with only 10% of the previous amount of energy. Net Biomass is denoted by Nbiomass symbol.

How to calculate Net Biomass using this online calculator? To use this online calculator for Net Biomass, enter Gross Primary Production (Ibiomass) & Gross Decrease in Biomass (Dbiomass) and hit the calculate button. Here is how the Net Biomass calculation can be explained with given input values -> 84 = 100-16.

### FAQ

What is Net Biomass?
The Net Biomass formula is defined as the amount of biomass left in the universe after the elevation of trophic level with only 10% of the previous amount of energy and is represented as Nbiomass = Ibiomass-Dbiomass or Net Biomass = Gross Primary Production-Gross Decrease in Biomass. Gross Primary production is the biomass produced by organisms over a period of time & Gross Decrease in Biomass is the loss moving upward the ecological pyramid as only 10% energy is transmitted to the next level.
