Based on the context provided, arrow 1 in the student's carbon cycle diagram likely represents the process of photosynthesis. During photosynthesis, plants take in carbon dioxide (CO₂) from the atmosphere and convert it into organic matter (such as glucose) using sunlight. This process is a crucial part of the carbon cycle, moving carbon from the atmosphere into the biosphere (specifically plants).
A student is developing a model of the carbon cycle, which involves the movement of carbon among various Earth systems. She begins by drawing the diagram shown below. What does arrow 1 represent? Atmospheric Carbon (CO, gas) Item 13 COURSE TOOLS Item 14 Item 15 Forest Fire Item 16 Item 17 Item 18 Item 19 Item 20 Dissolved CO, 5 6 Carbonate Rocks Fossil Fuels (coal, oil, and natural gas) Green Algae Carbon in Marine Sediments. < (1 point) Cellular Respiration Photosynthesis Combustion Consumption
