Nutrient Cycle

The chemical nutrients that are essential for the synthesis of living matter are taken from the physical environment. After the death and decomposition of living organisms, they are returned to the environment to be used over and again. This cyclic back …

Biosphere

The geologist Eduard Sues coined the term biosphere. The biosphere is characterized as a part of the earth, which includes ground and air. Moreover, the organisms on earth live in the biosphere. The biosphere is a confined area on the earth's surface whe…

Textbook Question

Chapter 43, Problem 7TYU

DRAW IT (a) Estimate the average CO₂ concentration in 1975 and in 2012 using the data provided in Figure 43.25. (b) On average, how rapidly did CO₂ concentrations increase (ppm/yr) from 1975 to 2012? (c) Estimate the approximate CO₂ concentration in 2100, assuming that the CO₂ concentration continues to rise as fast as it did from 1975 to 2012. (d) Draw a graph of average CO₂ concentration from 1975 to 2012 and then use a dashed line to extend the graph to the year 2100. (e) Identify the ecological factors and human decisions that might influence the actual rise in CO₂ concentration. (f) Discuss how additional scientific data could help societies predict this value.
