Which environmental condition is the primary cause for the formation of a carbon sink from un-recycled organic matter?

An abundance of sunlight for photosynthesis

High temperatures that speed up chemical reactions

A significant lack of decomposers like bacteria and fungi

The presence of many large herbivores consuming plants

A deep, cold-water bog has very low oxygen levels, which inhibits the growth of most bacteria and fungi. What would you most likely expect to find in the sediment layers of this bog?

Soil that is rich in nutrients and ready to support new plant life

A large accumulation of partially decomposed organic material, such as peat

Evidence of rapid and complete recycling of all plant and animal matter

Pockets of trapped atmospheric gases, primarily nitrogen

They are quickly released back into the air as carbon dioxide.

They are converted into nutrients and used by living plants.

They become physically trapped and unavailable for the atmospheric carbon cycle.

They are immediately transformed into fossil fuels through heat and pressure.

A temporary holding area where carbon is rapidly exchanged with the atmosphere.

A location where producers convert atmospheric carbon into organic matter.

A large, long-term repository where carbon is locked away from the active cycle.

A process that increases the amount of carbon dioxide available to plants.
