Answer:
all
Explanation:
Biogeochemical cycles are pathways by which nutrients flow between the abiotic and abiotic compartments of the Earth. The abiotic portion of the Earth includes the lithosphere (the geological component of the Earth) and the hydrosphere (the Earth’s water).
Ecosystems rely on biogeochemical cycles. Many of the nutrients that living things depend on, such as carbon, nitrogen, and phosphorous are in constant circulation.
Essential elements are often stored in reservoirs, where they can be taken out of circulation for years. For example, coal is a reservoir for carbon.
Humans can affect biogeochemical cycles. Humans extract carbon and nitrogen from the geosphere and use them for energy and fertilizer. This has increased the amount of these elements in circulation, which has detrimental effects on ecosystems.
There are three major forms of fossil fuels: coal<span>, </span>oil and natural gas<span>. All three were formed many hundreds of millions of years ago before the time of the dinosaurs – hence the name fossil fuels. The age they were formed is called the Carboniferous Period. It was part of the Paleozoic Era.</span>
Is the most resource-intensive
Recently, microalgae have been recognized as a promising platform for biofuels production and biorefineries. Microalgae have very high growth rates when compared with that of terrestrial plants, thereby demonstrating high CO2 fixation efficiency and high biomass productivity.
