Question
Chapter 56, Problem 2DA
Summary Introduction
To determine: The relationship among the habitat types between the NPP per unit area and the world NPP.
Introduction: The tropical rainforests are very rich in biodiversity and consists of one of the largest trees in the world. The trees can reach a height of about 30-45 meters and have broad leaves. The plants or trees are evergreen trees and have densest canopies.

You are studying primary productivity and biodiversity patterns of an ecosystem. The ecosystem is represented by the climatograph below. The Gross Primary Productivity (GPP) is measured to be 5000 grams of carbon per square meter per year, and the Total Respiration (RT) is measured to be 300 grams of carbon per square meter per year.
- What kind of biome is this?
- Calculate the Net Ecosystem Production (NEP) for this ecosystem
- What does the calculated NEP value indicate about the carbon balance and overall productivity of the ecosystem? (one sentence)
- Based on both the climatograph and the NEP, what can you say about the biodiversity of plants versus consumers?
Choice 1 of 4:plant biodiversity is greater than consumer biodiversity
Choice 2 of 4:consumer biodiversity is greater than plant biodiversity
Choice 3 of 4:consumer biodiversity is the same as plant biodiversity
Choice 4 of 4:lower plant biodiversity compared to consumer biodiversity
