carbon that is underground in the form of fossilized animals cannot be used in the carbon cycle unless humans extract it from the ground. when an element is stored in a part of the carbon cycle, what do we call it?\ngone forever\na nutrient sink
Answer
Answer:
B. a nutrient sink
Brief Explanations:
In the carbon cycle, when an element (like carbon) is stored in a particular part (such as underground as fossilized animals), it is called a nutrient sink. A nutrient sink is a reservoir that holds nutrients (including carbon) for a period of time. In this case, the underground fossilized carbon is a sink until human extraction allows it to re - enter the active carbon cycle. "Gone forever" is incorrect as carbon in such forms can re - enter the cycle through human activities (like burning fossil fuels).
