Question

release more carbon into the atmosphere than they take in.
classify each process as a carbon source or a carbon sink.
ocean loss ocean uptake respiration deforestation
carbon source carbon sink

Explanation:

• Ocean loss: Releases carbon into the atmosphere, so it is a carbon source.
• Ocean uptake: Absorbs carbon from the atmosphere, so it is a carbon sink.
• Respiration: Organisms release carbon dioxide during respiration, so it is a carbon source.
• Deforestation: Removes trees (which absorb carbon via photosynthesis) and may release stored carbon (e.g., if trees are burned), so it is a carbon source.

Answer:

• Carbon source: ocean loss, respiration, deforestation
• Carbon sink: ocean uptake
