Answer:
The Rhizaria are supergroup species of mostly unicellular eukaryotes and classified as protista. Rhizaria include species like cercozoa, foraminifera and radiolaria.
<u>Some of the attributes of Rhizaria are:</u>
- non-photosynthethic in nature, but some have a symbiotic relationship with unicellular algae.
- express only rDNA sequences so they can vary in different forms.
- do not have clear morphological characters
- they mostly includes amoebas which functions for food engulfing and help to direct movement in rhizarian protista.
<u>Contribution of Rhizaria to the ecosystem:</u>
- There are known as abundant bacterial grazers, and play very important role in microbial food webs.
- They provide a wide diversity of marine organisms.
- important contributors to oceanic carbon pools .
Hence, Rhizaria are important part of ecosystem.
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.
