Question

Carbon Cycle...

anyone understand the carbon cycle, i have this question for Bio I am stuck on and I already tried understanding my book. This is worth half of the quiz points so I really need to get it right.

Describe two paths carbon dioxide can take through the carbon cycle.

Yes, I know this is in the wrong section as well, I already tried in the Bio section and didn't get any replies.

Answer 1

wait what grade r u n ?

Answer 2

this is math btw.
You'd have more help going to science

Answer 3

I already said no one was there to help...

Answer 4

But I just did an assignment on Carbon Cycle so I could help

Answer 5

Ok...

Answer 6

o dang u guys r way ahead of me.

Answer 7

Carbon stored beneath the ocean floor is removed from the biological carbon cycle, entering the geological carbon cycle. Carbon converted to biological form in plants, consumed by animals, and returned to the atmosphere in respiration can travel this path over a very short period – days, weeks, or months. But carbon buried under the ocean floor might take tens of millions of years to return to the atmosphere, if it does at all. Throughout the Earth’s history, this emission of CO2 (and many other gases) from deep below the planet’s surface happens as geological events, such as volcanic eruptions.

Human beings tap into the geological carbon cycle by extracting oil and coal, which are both hydrocarbons, for use in automobiles and power plants. A byproduct of this combustion is CO2 gas. Since the Industrial Revolution began, carbon dioxide levels in the atmosphere have increased measurably, mostly as a result of human use of fossil fuels.

Humans have also altered the biological carbon cycle, increasing atmospheric CO2 levels, through forest clearing and land use. Trees store large amounts of carbon; when they die and decompose, much of this stored carbon is released as CO2. However, when humans clear large expanses of forest, primarily through the use of fire, the levels of atmospheric carbon are increased in two ways. First, during combustion, stored carbon is released directly into the air as CO2, and second, the clearing of land takes away a key mechanism for removing carbon dioxide from the atmosphere (via photosynthesis).

Since carbon dioxide is a primary greenhouse gas, many scientists argue that the increase in atmospheric CO2 from human activities has resulted in an enhanced greenhouse effect and could result in corresponding changes in our global climate, including higher global temperatures.

Answer 8

but good luck

Answer 9

Oh that looks great, that should really help...Thanks
