Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned while post-disturbance fallow vegetation is allowed to freely grow while the cultivator moves on to another plot. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the field is overrun by weeds. The length of time that a field is cultivated is usually shorter than the period over which the land is allowed to regenerate by lying fallow. This technique is often used in LEDCs (Less Economically Developed Countries) or LICs (Low Income Countries). In some areas, cultivators use a practice of slash-and-burn as one element of their farming cycle. Others employ land clearing without any burning, and some cultivators are purely migratory and do not use any cyclical method on a given plot. Sometimes no slashing at all is needed where regrowth is purely of grasses, an outcome not uncommon when soils are near exhaustion and need to lie fallow. In shifting agriculture, after two or three years of producing vegetable and grain crops on cleared land, the migrants abandon it for another plot. Land is often cleared by slash-and-burn methods—trees, bushes and forests are cleared by slashing, and the remaining vegetation is burnt. The ashes add potash to the soil. Then the seeds are sown after the rains.

Do you think there is a biosphere in space? Why or Why not?
Answer: By the most general biophysiological definition, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere. Process. Humans live in a “comfort zone” close to the surface of the Earth, but there are many species that live outside of this comfort zone. Although the biosphere measures about 20 kilometers (12 miles) from top to bottom, almost all life exists between about 500 meters (1,640 feet) below the ocean's surface to about 6 kilometers (3.75 miles) above sea level. The biosphere has existed for about 3.5 billion years.

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.

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.

which African region or feature is this paragraph describing?
A. The Sahel
B. The Sahara
C. The Savannas
D. The Rain Forest
Answer:
The paragraph is describing the savannas.
Explanation:
Africa is a continent almost entirely dominated by torpical types of climates and in accordance with that tropical types of biomes, with only very small parts of Africa belonging to the Mediterranean climate and biome. The biome in Africa that seems to have traditionally been the best for a living is the savanna, and when it comes to people living in a traditional manner it still seems to be the best place for it.
The people that live in the savanna tend to make shelters from dirt, grasses, and sticks, thus not very strong ones, mostly because of the climate. The majority tend to be herders, so their diet mostly consists of milk and milk products and meat. In more recent times though, the people living in the savanna tend to engage more with the rest of the world through providing services as safari guides or by exhibiting traditional dances and rituals in front of tourists. This has become a way to earn some money, which has led to slight modernization of these societies.

What is a river?A river is a natural stream of water that flows or starts from its source until its mouth, where a river finally discharges its water. A river can discharge its water into another river, a lake or the sea.
A river can receive water from different sources: Precipitation or rainfall; Surface runoff; Springs and seepage water; water from snowmelt in areas with snow and glaciers.
In mountainous and hilly areas, rainwater flows and concentrates in lower areas, which fill up to form lakes. When the river flows through lowlands, the channel will erode the outer banks of bends, depositing sediment and generating a flood plain, until it reaches its mouth.
