The suspended load of a stream usually consists of fine sand, silt, and clay particles consists primarily of highly soluble substances is deposited before the bed load moves along the bottom of the channel by rolling or sliding

The correct answer is option A, usually consists of fine sand, silt, and clay particles

Explanation:

The suspended load of a stream consists of small particle particularly clay, silts and fine sands. During the process of sediment transportation, sediment at the bottom of a channel gets uplifted and remain suspended due to their small size. A suspended sediment load do not cause erosion as it is not in the frictional contact of the stream bed.

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.
