Heavy sedimentary items such as as rocks for example <span />
My Answer: RNA molecules
Why?: " <span>Catalysts with this special self-promoting property can use raw materials to reproduce themselves and thereby divert these same materials from the production of other substances."
Hope I helped! :D</span>
Floodplain refers to a region of low-lying land adjacent to a river, produced primarily of river sediments and are subjected to flooding. Thus, floodplain can be correctly matched with a strip of land next to a river that is usually very fertile.
Bed load signifies towards the particles in a flowing medium, generally water, which is translocated along the bed. The bed load comprises of small or large boulders and moves by sliding, rolling, and/or hopping (saltating). Hence, bed load can be correctly matched with large boulders carried along by a river.
Suspended load refers to the part of the sediment, which is conducted via a flow of fluid that settles gradually enough like that it almost never touches the bed. It is held in suspension via the turbulence in the flowing water and comprises particles usually of the fine silt, salt, and clay size. Hence, the suspended load can be correctly matched with small rocks carried along by a river.
Headwaters are witnessed in the upstream of the river, the source of the headwaters is generally its starting point, that is, it can be a marsh fed upstream, or from an underground area. Hence, headwater can be correctly matched with the beginning of a river.
The perfect word for the blank is decomposers. Fungi and bacteria are decomposers. When plants and animals die, they become food for these organisms. Decomposers convert their food into nutrients like carbon and nitrogen that are released back into the soil, air and water.
