Question

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 _______.

Answer 1

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.

Step-by-step explanation:

ammonia

1%

consuming

combustion

rainfall

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.
