Summary Introduction

To determine:

The nutrient nitrogen and phosphorus that necessary for Calvin cycle to function photosynthesis, often limit the primary production in an ecosystem.

Introduction:

Primary production provides the origin of energy in an ecosystem, it is the chemical energy generated by fixation of carbon dioxide during photosynthesis and chemosynthesis. Primary production is the source of energy for the entire organism from bacteria to humans. Photosynthesis involve the Calvin cycle that makes sugar from carbon.
