The primary productivity of the biome

Compare the primary productivity of the biome you chose referencing the “Net Primary Productivity” figure. It is high or low? Why? Describe how carbon cycles into, around, and out of soil. What is the role of vegetation in that process?

The roles of nitrifying bacteria

Describe the specific roles of nitrifying bacteria, decomposers, and denitrifying bacteria in the plant/soil ecosystem. How are they similar? How are they different? How do microbes change the number of carbon compounds in the soil and carbon dioxide in the air?

The feedback mechanism

Describe and explain at least one feedback mechanism that would further increase global temperatures once a warming trend has started.  What is the overall trend in global temperature since 1880?

The partial melting

Describe how partial melting of the mantle produces a mafic (basaltic) composition at a mid-ocean ridge. Given an igneous rock name/type (e.g. gabbro) what are the typical physical characteristics for that rock composition (e.g., magma/lava viscosity, SiO2 content, temperature, mineral percentages, etc.).

The cultural-geographic conditions

Give an account of the countries’ cultural-geographic conditions: Population (size, birth rate, death rate, life expectancy, business, economy (GDP), prosperity (HDI) (+ any other things you consider relevant) You can advantageously present this information in tabular form

The stratospheric ozone

The only form of ozone that the climate & environmental field is concerned with is stratospheric ozone because it protects the contents on the surface of the earth from harmful shortwave solar radiation (UV). Explain
