Cyanobacteria produce from nitrogen gas as part of the nitrogen cycle.

Only about of Earth's water is available to be consumed by humans or used for agriculture.

Animals cannot consume nitrates directly. They must obtain nitrogen by plants or other herbivore animals.

from forest fires and volcanoes, as well as the decay of dead plants and animals, causes a type of pollution from carbon oxides.

One of the primary reasons that freshwater is unevenly distributed around the world is due to variation in amounts of .

Respond to the following based on your reading.

Briefly summarize how decomposition of plant and animal remains and plate tectonic forces can lead to the formation of fossil fuels.

Plant and animal matter decay at the bottom of a body of water and become buried in sediments, forming kerogen. Plate tectonic forces can increase the pressure and temperature of the kerogen. This can cause hydrocarbons to release, and these hydrocarbons accumulate in underground reservoirs.
