The Carbon Cycle
Siužetinės Linijos Tekstas
- Hi, I'm Mark. Today, I saw some rocks and sediment being transported to a factory nearby me. Then, I noticed the fuels coming out of it. The smoke coming out of the factory was carbon dioxide.
- Then, that carbon dioxide went up in the air. It was now part of the atmosphere.
- CO^2
- I know that the plants on the earth absorb the CO2 to grow. After that, through photosynthesis, and using that carbon dioxide these plants grow fully.
- The water from ponds and oceans also absorbs the carbon from the atmosphere.
- The carbon goes through the cow's digestive system and is then disposed. To this.
- Those plants become food for the animals. The carbon moves from the plants to the animals. Speaking of animals, I saw a cow close by the field I was at today, and I noticed that the cow was eating some of the plants (grass), taking in carbon from them.
- In the end, the same thing happens all over again. The carbon cycle repeats itself, when the animal dies and decomposes. But that got me wondering... During one of those other times, what if something else occurs during the cycle? Like a forest fire.
- It just stays up there! More and more CO2 is being released into the atmosphere, without getting absorbed by any of the plants and/or animals... Excess carbon in the atmosphere warms the planet and helps plants on land grow more. But this is way too hot. Get me out of here Mark!
- In this case, all the plants and trees have gone up in flames. Everything is burned. So all that carbon dioxide that's in the air... What happens to it now..? Where it cannot be absorbed by any plants on the land?
