Question

questions 1 through 3 refer to the following. the diagram below shows a simplified carbon cycle. based on the diagram above, which process most directly results in the storage of carbon as coal and oil over millions of years? a photosynthesis b cellular respiration c decomposition d burning of fossil fuels

Explanation:

To determine the process that stores carbon as coal and oil over millions of years, we analyze each option:

• Option A (Photosynthesis): Converts CO₂ to organic matter but doesn't directly form fossil fuels over millions of years.
• Option B (Cellular Respiration): Releases CO₂, not storing carbon as fossil fuels.
• Option C (Decomposition): Breaks down organic matter. Over long periods, decomposition of dead organisms, along with geological processes, leads to the formation of fossil fuels like coal and oil as carbon is stored in these materials over millions of years.
• Option D (Burning of Fossil Fuels): Releases carbon from fossil fuels, not storing it.

So, decomposition is the process that, over millions of years, results in carbon storage as coal and oil.

Answer:

C. Decomposition
