Answer:

Upwelling

Explanation:

Upwelling is the process through which cold water gets to ascends from the bottom, providing nutrients to the superficial stratum.

Upwelling is an ascending displacement of marine currents. The phenomenon<em> can also occur in lakes or freshwater dams</em>.

Wind blowing over the coast can cause surface water to move out to sea. This motion is complemented by a slow ascension of cold water coming from the bottom forward to the coast. This currents movement is known as upwelling.

Upwelling water is extremely cold and rich in nutrients, which result from remineralization, by bacterial action, of organic matter that accumulates in the deepest stratum of the water body.

The contact of minerals with photosynthesizing organisms in superficial layers produces a significantly high primary productivity.

When did the curds of the universe eventually become?
aniked [119]
The ultimate fate of the universe is a topic in physical cosmology, whose theoretical restrictions allow possible scenarios for the evolution and ultimate fate of the universe to be described and evaluated. Based on available observational evidence, deciding the fate and evolution of the universe have now become valid cosmological questions, being beyond the mostly untestable constraints of mythological or theological beliefs. Many possible futures have been predicted by different scientific hypotheses, including that the universe might have existed for a finite and infinite duration, or towards explaining the manner and circumstances of its beginning.
