Question

Quizplus · Accepted Answer

Biochemical oxygen demanding wastes (BOD) refer to organic biodegradable material that requires oxygen to be decomposed by bacteria. This includes human and animal waste, food waste, and other organic material. Phosphorus and nitrogen-based fertilizers (A) contribute to nutrient pollution in water, while sand, silt, and clay suspended in water (B) can cause sedimentation and turbidity. Fish, aquatic insects, algae, and other live aquatic organisms (C) are not considered BOD waste, as they are naturally occurring in aquatic environments.
