Adding organic materials, such as sewage or paper pulp, to water stimulates the consumption of which chemical by decomposers?

Decomposers breaking down added organic matter like sewage or paper pulp consume dissolved oxygen from the water.

Carbon dioxide is released by this decomposition rather than consumed.

Salts are not the resource decomposers draw on during this breakdown.

Minerals are freed as nutrients, not used up as the key demand here.

The heavy draw on dissolved oxygen is what defines biochemical oxygen demand.

Falling oxygen can suffocate fish and other aquatic life in polluted waters.
