Question

Up arrows are used to indicate processes that cycle carbon into the atmosphere and down arrows are used to indicate processes that cycle carbon out of the atmosphere.

Drag each item to the correct location to model the flow of carbon into and out of the atmosphere. Some choices may be used more than once or not at all.

burning fossil fuels, photosynthesis, respiration,
equilibrium with the ocean, limestone formation

Answer 1

Up arrows indicate processes that cycle carbon into the atmosphere, while down arrows indicate processes that cycle carbon out of the atmosphere.

Step-by-step explanation:

The flow of carbon into and out of the atmosphere can be modeled using arrows. Up arrows indicate processes that cycle carbon into the atmosphere, while down arrows indicate processes that cycle carbon out of the atmosphere. To model this, we can use the following:

• Photosynthesis: This process uses carbon dioxide from the atmosphere to produce organic carbon compounds, effectively cycling carbon out of the atmosphere.
• Respiration: This process releases carbon dioxide into the atmosphere as a byproduct, cycling carbon back into the atmosphere.
• Burning fossil fuels: This process releases large amounts of carbon dioxide into the atmosphere, cycling carbon back into the atmosphere.
• Equilibrium with the ocean: The ocean acts as a carbon sink, absorbing and storing carbon from the atmosphere. This can be represented by a down arrow, indicating that carbon is being cycled out of the atmosphere.
• Limestone formation: Limestone formation is a long-term geological process that removes carbon dioxide from the atmosphere and stores it in the form of limestone rock. This can also be represented by a down arrow, indicating that carbon is being cycled out of the atmosphere.
