(a)

Summary Introduction

To determine: The other variable needs to known for calculating the net ecosystem production (NEP) if the NPP is known.

Concept introduction: Net ecosystem production (NEP) is the gross production remain after the loss of total respiration of all the organisms in the system, on the other hand the NPP can be expressed as the amount of novel biomass added by producers in that time.

(b)

Summary Introduction

To determine: Why it is difficult to measure a variable that involves in net ecosystem production (NEP) ocean.

Concept introduction: Net ecosystem production (NEP) is the gross production remain after the loss of total respiration of all the organisms in the system, on the other hand the NPP can be expressed as the amount of novel biomass added by producers in that time.
