When Charles Darwin stepped ashore on the Galapagos Islands in September 1835, it was the start of five weeks that would change the world of science, although he did not know it at the time. Among other finds, he observed and collected the variety of small birds that inhabited the islands, but he did not realize their significance, and failed to keep good records of his specimens and where they were collected.

Answer:II) Deforestation and suburbanization reduce an area's net primary productivity.
III) Increasing atmospheric concentrations of carbon dioxide could alter Earth's climate.
IV) By using fossil fuels we are destroying a nonrenewable resource.
Explanation:
The global carbon cycle can be defined as the cycle of carbon in which the carbon is transformed and changed into forms while transferring to atmosphere, land, ocean and in the form of fossil fuels.
The deforestation and suburbanization processes will likely to affect the contribution of the plant in the net primary productivity generate due to photosynthesis process that involves the production of carbon products in the form of glucose by atmospheric carbon dioxide.
The increase in atmospheric concentration of carbon dioxide through the burning of fossil fuels is likely to warm the earth climate. The burning of fossil fuel is likely to increase the abundance of carbon dioxide in the air.
The fossil fuels are the source of non-renewable resource utilized for the purpose of generation of thermal energy. These resources once consumed will not get replenished thus this will reduce the carbon level produced due to burning of fossil fuels in the future.
Temp causes water to rise or sink through convection, and salinity affects the density of the water, so higher salinity water will contribute to deep water currents
