Please help: What effect does eutrophication have in aquatic ecosystems?
A. It prevents sunlight from reaching aquatic life below the waters surface
B. It negatively impacts aquatic vegetation but is beneficial for all aquatic animals
C. It decreases carbon dioxide concentration, which is harmful for aquatic animals
D. It lowers the concentration of nitrogen and phosphorus available to marine animals
Answer:
The answer is D
Explanation:
an overabundance of nutrients primarily nitrogen and phosphorus which is in the water starts a process called eutrophication which makes it decrease. when the algae dies they are decomposed by bacteria. This process consumes the oxygen dissolved in the water which is needed by fish and other Aquatic Life to breathe.
It isn't C because it actually increases carbon dioxide not lower.
It isnt B because it does negatively impact aquatic vegetation but it is not beneficial for all aquatic animals
A isn't the the correct answer because eutrophication has nothing to do with sunlight into the ocean
So the only answer left which is correct is D
(I hope this helps you! have a wonderful day everyone!)
:)
The effect of eutrophication on the aquatic ecosystem is that it reduces the concentration of nitrogen and phosphorous content in the atmosphere available to marine animals.
Option D is the correct answer.
What is an ecosystem?
An ecosystem is an area where the habitats like plants, organisms, humans, etc. are living.
Eutrophication is a natural process where the minerals and nutrients like nitrogen, phosphorous, etc. are increased in a high amount. This leads to the emergence of algae, and marine animals like fishes get died.
Therefore, the content of nutrients gets reduced as needed by the aquatic animals due to the process of eutrophication.

In what year did the German Democratic Republic (GDR) and the Federal Republic of Germany (FRG) unify? What kind of government was formed?
Answer:
I didn't know so I googled this one. Below
Explanation:
German Reunification Treaty
The two original copies of the Unification Treaty signed on 31 August 1990. West German Interior Minister Wolfgang Schäuble signed for the FRG and the East German State Secretary Günther Krause signed for the GDR.
Reunified Germany: 1990–present
Cold War (West East): 1945–1990
Occupation Ostgebiete: 1945–1952
Reunification New states: 1990
As a result, the German Democratic Republic was abolished on Unification Day, October 3, 1990, and the Federal Republic of Germany incorporated five newly formed federated states that were once part of the German Democratic Republic.
What are the federated states?One of the constituent parts of a federation is a federated state, which has its own boundaries and a constitution. These states are different from completely sovereign states in that.
A federation, usually referred to as a federal state, is a political organisation that consists of a union of largely self-governing provinces, states, or other territories that are governed by a single federal government.
As a fully fledged federated city-state, East and West Berlin were unified and incorporated into the Federal Republic. They do not possess all sovereign powers because those have been split between the federated states and the federal or central authority.
