How Did Tilapia Change Lake Victoria ?

Answers

Answer 1

Answer:

The second option and/or third option is correct.

Explanation:

I did a case study on the addition of Tilapia to Lake Victoria with OneWorld.

The effects are listed in our publication.

"In efforts to improve food production and bolster the fish-export business in Eastern Africa, the Tilapia was introduced to Lake Victoria, the largest tropical lake in the world, which serves as the main source of sustenance for the people of Kenya, Tanzania, and Uganda. Instead of improving the fishing opportunities in the lake, however, the Tilapia has caused the decimation of several fish populations.

Tilapia’s aggressive and omnivorous feeding behavior outcompeted native species or utilized native species themselves as a food source. Indigenous cichlids play a major role in reducing detritus, but with severely decreased numbers, their ability to consume this organic material is diminished. As the detritus decays and sinks to the lake floor, it absorbs oxygen. The decimated cichlid population led to unprecedented amounts of detritus, which has depleted oxygen at the lowest levels of the lake and created dead zones. Lake Victoria, considered one of the most species-diverse lakes in the world, has seen its cichlid population drop from 400 to 200 species due to the introduction of the Tilapia and other invasive species, such as the Nile Perch."

40. The factor that would cause the supply
curve to shift to the right is
A. higher taxes
B. a decrease in government subsidies
C. an increase in the cost of resources
D. an increase in the number of sellers

Answers

Answer:

D. an increase in the number of sellers

Explanation:

In Economics, there are primarily two (2) factors which affect the availability and the price at which goods and services are sold or provided, these are demand and supply.

The law of demand states that, the higher the demand for goods and services, the higher the price it would be sold all things being equal. On the other hand, law of supply states that the higher the price of goods and services, the lower the supply.

Also, in order to understand both short-run economic fluctuations and how the economy move from short to long run, we need the aggregate supply and aggregate demand model.

Aggregate supply (AS) refers to the total quantity of output (goods and services) that firms are willing to produce and sell at a given price in an economy at a particular period of time.

An aggregate supply curve gives the relationship between the aggregate price level for goods or services and the quantity of aggregate output supplied in an economy at a specific period of time.

Hence, the factor that would cause the supply curve to shift to the right is an increase in the number of sellers because the quantity of aggregate output supplied to the market would increase i.e an increase in the quantity of goods supplied by the suppliers.

U.S. debt not secured by real estate exceeds $3 trillion.
True
False
HELP ASAPPPO ):

Answers

Answer:

Explanation:

True

The number is far too small.

A debt secured by real estate would be a legitimate use of debt and borrowing.

The Federal Government by itself (in the United States) has a debt over 20 trillion. It can never be paid back in our life time. To show you how enormous the debt is take 20 trillion and divide it by 330,000,000 which is the population of the United States.

20 Trillion has 12 zeros behind it.

20 000 000 000 000 / 330 000 000 = 2000000 / 33 = 61 000

That means that every man woman and child in America would have to pay 61000 dollars to clear just the Federal debt. The states all have similar outrageous amounts owing. Then there's the municipalities which also have debt.

Especially after the pandemic, these numbers are likely very small. Question: could your family pay 61000 each to get out of debt? Mine could not and there are only 3 of us.

Why is democracy the best practice in the world?

Answers

Answer:

The way I see this is less a question on whether or not democracy is good, but whether it's within suitable boundaries to work correctly. The overarching state exists to keep a certain order, and, if someone is to see that status quo as bad, they often won't see a point to voting. If you agree don't think this, you should engage in discussion with them about the current status quo. If you do, you should try to find the least bad candidate if you choose to vote, while focusing on actions outside of a ballot.
