Human activity has had a significant impact on the carbon cycle as it relates to the ocean. Activities such as combustion of fossil fuels and land use changes have led to a new flux of CO2 into the atmosphere. The increases of CO2 in the atmosphere have led to much of the excess being stored in the ocean, causing the pH of the ocean to decrease, becoming more acidic. The effects of ocean acidification include all BUT:



A)Increasing acidity speeds the death and decomposition of many ocean plantsB)The resulting increase in acidity changes the balance of minerals in the water. C)Increasing acidity impacts ocean life, including, depressing metabolic rates in jumbo squid, depressing the immune responses of blue mussels, and coral bleaching. D)It is more difficult for corals and shelled marine organisms to produce calcium carbonate, which is the main ingredient in exoskeletons or shells, making it more difficult for these animals to survive.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
