Which of these can decrease due to fertilizer in waterways? oxygen, nitrogen, bacteria, algae

The correct answer is oxygen.

The agricultural runoff result in carrying away the fertilisers in the water bodies. The nutrients present in the fertilizers allow the blooming of the algae, the extensive growth of algae block the water ways. Due to presence of large colonies of algae, a large number of algae die. The dead algae sink into bottom and decompose, which removes the oxygen from the water.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
