Under what conditions might sediment in water or cultural eutrophication be beneficial?

Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases the primary productivity of the ecosystem. Depending on the degree of eutrophication, subsequent negative environmental effects such as anoxia and severe reductions in water quality, fish, and other animal populations may occur. Cultural eutrophication refers to such problems when caused by man's everyday activities. The eutrophication of the Potomac River would be an example. Most people worry about contaminated sediments in water.
However, natural sediments form by weathering of rock. They then erode from the site of weathering and are transported by wind, water or ice operating under the influence of gravity. This is a normal ongoing process and not detrimental to ecosystems.

Which of the following conditions are necessary to cause loose sediment to become sedimentary rock?
There are no following conditions. Pressure will make loose sediment into rock, the pressure may derive from the weight of water or other rocks above the sediment.
What are the beneficial effects of flooding?
There are only a few beneficial effects of flooding. Flooding will hydrate areas that are normally pretty dry for example.
Are there positive effects from floods?
yes, the positive effect of a flood would have to be that it spreads sediment containing beneficial nutrients to topsoil that might never arrive there otherwise.
Is a sediment rock?
Sediment is the stuff that settles at the bottom of a liquid (such as the bottom of a pond). It can include sand and pebbles but also dead plants and animals. If conditions are right, the sediment can dry out and turn into a sedimentary rock (a rock made from sediment). Sedimentary rocks can contain fossils of plants or animals that fell into the "muck" at the bottom of a body of water. Cool, huh?
Certain blank that form sediment are considered an indicator species?
Certain microorganisms, such as diatoms and foraminifera, that form sediment are considered indicator species. These organisms have specific habitat requirements and environmental tolerances, so their presence or absence in sediment can provide valuable information about the conditions of their habitat, including water quality, temperature, salinity, and nutrient availability. Their abundant fossil record in sediment also aids in paleoenvironmental reconstructions.
