because of global warming, permafrost has been melting causing carbon dioxide to be released into the atmosphere through\nhydrolysis\ndecomposition\nphotosynthesis

Answer

Brief Explanations:

When permafrost melts due to global - warming, the organic matter within it undergoes decomposition by microorganisms. This decomposition releases carbon dioxide into the atmosphere. Hydrolysis is a chemical reaction involving water and a compound, not relevant here. Photosynthesis absorbs carbon dioxide, not releases it in this context.

Answer:

decomposition
