All of this extra carbon needs to go somewhere. So far, land plants and the ocean have taken up about 55 percent of the extra carbon people have put into the atmosphere while about 45 percent has stayed in the atmosphere. Eventually, the land and oceans will take up most of the extra carbon dioxide, but as much as 20 percent may remain in the atmosphere for many thousands of years.
The changes in the carbon cycle impact each reservoir. Excess carbon in the atmosphere warms the planet and helps plants on land grow more. Excess carbon in the ocean makes the water more acidic, putting marine life in danger
The last supper ended disastrously because the type of paint quickly faded and chipped off. (I just searched this on the internet and found this there easy to find)
Well everything is made of complex proteins. There isn't one single organism just comprised of proteins. For example keratin is a protein that is made when RNA passes through a ribosome. Now this protein may be used in different functions, one is to strengthen hair/nails. To simplify: anything living that is eukaryotic. (multi_cellular organisms bigger than bacteria and viruses.)
