The net primary productivity of cultivated land is most similar to the net primary productivity of which ecosystem?

Answers

Answer 1

The net primary productivity of cultivated land is most similar to the net primary productivity of the temperate grassland. Temperate grassland is a terrestrial ecosystem whose main plants consist of shrubs or grass. The environment is temperate and it ranges from semi-humid to semi-arid.

Answer 2

The net primary productivity of cultivated land is probably most similar to that of tall-grass prairies or temperate deciduous forests, which have significant natural productivity, unlike the extremes of tropical rainforests or deserts.

The net primary productivity (NPP) of cultivated land can be compared to various natural ecosystems based on their energy accumulation and conversion efficiency. As the table provided does not specify the exact NPP of cultivated land, we must infer based on general knowledge about ecosystems. Typically, cultivated lands have moderate to high NPP due to human management, including the use of fertilizers, irrigation, and crop breeding, to optimize production. Therefore, the NPP of cultivated land might be most similar to ecosystems like tall-grass prairies or temperate deciduous forests, which have substantial natural productivity and are often associated with fertile soils and favorable water availability. Cultivated land's productivity generally would not match that of a tropical rainforest, which has the highest NPP, nor would it be as low as a desert ecosystem.

The gulf of mexico's "dead zone" is caused by high levels of ____ in the mississippi river.

Answers

The Gulf of Mexico's "dead zone" is caused by high levels of plant fertilizer in the Mississippi River.

Final answer:

The Gulf of Mexico's dead zone is primarily caused by high levels of nitrogen and phosphorus from fertilizer runoff, leading to eutrophication and hypoxic conditions harmful to marine life.

Explanation:

The Gulf of Mexico's "dead zone" is caused by high levels of nitrogen (N) and phosphorus (P) in the Mississippi River. These elements act as fertilizers in the water, promoting excessive algae growth. When the algae die, they are decomposed by aerobic bacteria, which consume vast amounts of oxygen from the water. This process, known as eutrophication, leads to low dissolved oxygen (DO) levels and creates a hypoxic or "dead" zone — an expansive area severely depleted of marine life. The prominent dead zone in the Gulf of Mexico has significant negative impacts on the fishing industry due to massive fish kills, affecting ecological balance and the economy along the Gulf Coast. The runoff primarily comes from farm fields in the Midwest and is washed down the Mississippi River into the Gulf.

Why is there a difference between a lunar day and a solar day?

Answers

Unlike a 24-hour solar day, a lunar day lasts 24 hours and 50 minutes. This occurs because the moon revolves around the Earth in the same direction that the Earth is rotating on its axis. Therefore, it takes the Earth an extra 50 minutes to ''catch up'' to the moon.
Hope this helps... please mark brainliest.
Final answer:

The difference between a solar and lunar day is in the time each takes. A solar day is the time it takes for Earth to rotate once on its axis relative to the Sun, while a lunar day is the time it takes for the Moon to return to the same relative position to the Sun, as viewed from Earth. The lunar day is slightly longer due to Earth's movement along its orbit around the Sun.

Explanation:

The difference between a solar day and a lunar day arises from the movements of Earth and the Moon. A solar day, which we typically think of as a 24-hour day, is the time it takes for the Earth to complete one full rotation on its axis. This rotation is relative to the Sun, thus it's called a 'solar day'.

On the other hand, a 'lunar day' is the time it takes for the Moon to complete one full rotation on its axis and return to the same position relative to the Sun as viewed from Earth. This is a bit longer - about 24 hours and 50 minutes - because as the Earth is rotating on its axis, it's also moving along its orbit around the Sun. So, the Moon has to 'catch up' to align with the Earth and Sun again.

Rowland and molina's work showed that ultraviolet light in the stratosphere causes cfcs to release ________ atoms.

Answers

The answer is - chlorine.
When the CFC's are bellow the ozone layer they are protected by it from the ultraviolet light because the ozone absorbs big portion of it. But once the CFC's go above the ozone layer, things change immediately. They do not have the ozone protection anymore, and the CFC molecules are totally exposed to 'bombarding' from the Sun's ultraviolet energy, and than their molecules break up and release chlorine atoms. Chlorine atoms than react with the oxygen atoms in the ozone and form chlorine monoxide, which than leaves an ordinary oxygen molecule, thus damaging the ozone layer.

As many as ____% of individuals with eating disorders today are males.​

Answers

males in the U.s that have eating disorders are 10% - 15%

Approximately 10% of individuals with eating disorders are males, including serious conditions such as anorexia nervosa and bulimia nervosa. Studies show that males can also have a distorted body image, such as muscle dysmorphia, requiring prevention and tailored treatment.

As many as 10% of individuals with eating disorders today are males. This estimation includes disorders such as anorexia nervosa and bulimia nervosa which, while historically associated more with females, significantly impact males as well. The lifetime prevalence rate of bulimia nervosa, for example, is estimated at around 1% for women and less than 0.5% for men. A comprehensive study involving over 9,000 young males in the United States found that approximately 5.5% of them manifested elevated eating disorder risk. It's essential to recognize that eating disorders in males often involve a distorted sense of body image, including conditions such as muscle dysmorphia, where there is an extreme desire to increase muscularity. Due to the seriousness of these conditions and the potential for high mortality rates, comparable with opioid addiction, prevention and appropriate treatment tailored to the physical, emotional, and social needs are crucial.

Evaluate whether political, economic, environmental, or ethnic forces have a greater impact on territoriality and explain why.

Answers

All of these factors play a big role in territoriality, but in modern times, the leading ones are the economic factor (as a primary), and the political (close behind it). Nowadays everything is dictated by economy, so it plays the most important part in territoriality. People tend to be pleased when they have enough money and their own property, and the other factors are not so important. The economic factor is the basis for the political one, because the politics are based on economics, so people do not pay attention to politics while they are standing well economically. The environmental and ethnic factors, are primarily used as an instrument for the realization of some interest by the two other factors nowadays, they are a very mighty tool, but are used and are very influential when the other two, especially the economics are not working well.

Poland’s energy resources can be described as _____.
a. based on large deposits of coal
b. rich in petroleum
c. large deposits of sulfur
d. large deposits of copper

Answers

For energy resources, Poland's most important one is coal (and also lignite) which is mined in Upper Silesia in some large open pits mined there since the 19th century at least. It does have some petroleum in the Baltic Sea but still must import it from Russia.

ANSWER:

Poland’s energy resources can be described based on large deposits of coal.

EXPLANATION:

Poland's energy resources depend on the large deposits of coal in all forms- hard as well as soft. Most of the energy requirements in Poland are met by hard coal. Coal is used for generating electricity in Poland. Most of the power generating plants work on hard and brown coal. However, the government of Poland is now trying to 'use renewable energy sources' for the generation of electricity. Natural gas is one option that is being used as an alternative to coal for meeting the energy needs of Poland.

Answer:

The development of the Amazon Basin has caused soil erosion

Explanation:

Soil erosion is defined as the wearing away of topsoil which is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. One of the main reason for soil erosion is deforestation. Amazon being the largest rain forest in the world is in danger due to its development.  More than 20 percent of the Amazon rain forest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year.

Explain why some partly molten material rises toward earths surface

Answers

because its not as dense as whats in the middle

Answer:

Sometimes, some partly molten material rises towards the Earth's surface because either it gets added to the magma in the due course of the upward movement of magma and the magma doesn't get enough to melt it completely, or the material consists of elements with extremely high melting points.

Explanation: The magma carries molten material from the mantle towards the surface of the Earth. In its course of rising up, sometimes some materials get added to it after it is just about to reach the Earth's surface. Such material doesn't melt completely and reaches the surface in a partly molten form. In other cases, the magma consists of elements with melting points above 1200° Celsius to 1300° Celsius. Such materials sometimes reach the Earth's surface in a partly molten form.

In the last 800,000 years, in a span of 1,000 years it never happened that the CO2 go upwards or downwards for more than 30 ppm. It has always been a slow process in this period and as much as the jumps were big, that never surpassed this number. On the other hand we are witnessing that this has happened nowadays in just 13 years, and that is very concerning because such rapid changes of CO2 in the atmosphere brings rapid changes in the climate and it will be a global catastrophe if this trend continues.
