Question

rths processes climate change carbon cycle and the ocean (1 point) carbon is destroyed when organisms die the amount of carbon stays constant and simply cycles through animal respiration contributes the most carbon to the cycle brand - new carbon is generated when factories burn fossil fuels

Explanation:

• For the option "Carbon is destroyed when organisms die": According to the law of conservation of matter (in the carbon cycle context), carbon is not destroyed but recycled, so this is incorrect.
• For the option "The amount of carbon stays constant and simply cycles through": The carbon cycle involves the movement of carbon through different reservoirs (atmosphere, biosphere, geosphere, hydrosphere) without creating or destroying carbon, so the total amount remains relatively constant as it cycles. This matches the principles of the carbon cycle.
• For the option "Animal respiration contributes the most carbon to the cycle": Processes like decomposition, fossil fuel burning, and plant respiration (along with ocean uptake and release) also contribute significantly, and animal respiration is not the primary contributor.
• For the option "Brand - new carbon is generated when factories burn fossil fuels": Burning fossil fuels releases stored carbon (from ancient organisms) back into the atmosphere; no new carbon is created (law of conservation of matter), so this is incorrect.

Answer:

B. The amount of carbon stays constant and simply cycles through
