Question
Chapter 55.2, Problem 3CC
Summary Introduction
To predict: How the NEP (net ecosystem production) of a forest that was heavily burned by a wild fire changes over time.
Concept introduction: In an ecosystem, the total primary production is said to be the GPP (gross primary production). NPP or net primary production is equal to about half of GPP. NEP is defined as the measurement of total biomass accumulation at a particular interval of time.

WHAT IF? Suppose a developer proposes to clear-cuta forest that serves as a corridor between two parks. Tocompensate, the developer also proposes to add the samearea of forest to one of the parks. As a professional ecologist, how might you argue for retaining the corridor?
WRITE ABOUT A THEME: Energy and MatterDecomposition typically occurs quickly in moist tropicalforests. However, waterlogging in the soil of some moisttropical forests results over time in a buildup of organicmatter called “peat.” In a short essay (100–150 words), discussthe relationship of net primary production, net ecosystemproduction, and decomposition for such an ecosystem. AreNPP and NEP likely to be positive? What do you think wouldhappen to NEP if a landowner drained the water from atropical peatland, exposing the organic matter to air?

This translates into4.9 ha of the average American’s 7.2-ha ecological footprint.Another way to think about our footprint, however, is to estimatehow much land would be needed to grow biomass with anenergy content equal to that of the fossil fuel we burn.Assume that you are an average American who burns about6.3 metric tons of oil-equivalent in fossil fuels each year andthat average terrestrial net primary productivity (p. 32) can beexpressedas 0.0037 metric tons/ha/year. Calculate how manyhectares of land it would take to supply our fuel use by presentdayphotosynthetic production.
