Which of the following best describes the fate of energy in ecosystems?

Answers

The fate of energy in ecosystems is for it to be lost as heat. Energy "flows" through the ecosystem in the form of carbon-carbon bonds. When respiration occurs, the carbon-carbon bonds are broken and the carbon is combined with oxygen to form carbon dioxide. This process releases the energy, which is either used by the organism (to move its muscles, digest food, excrete wastes, think, etc.) or the energy may be lost as heat.All energy comes from the sun, and that the ultimate fate of all energy in ecosystems is to be lost as heat.

Answer:

It's best to also include the options since this is a multiple choice question! But the best answer would be D.

Explanation:

It flows through and is used by ecosystems.

How long would it take a sound wave from a car alarm to travel 1 km if the temperature is 0 degrees Celsius

Answers

The speed of sound in dry air at 0°C is 331.3 meters per second.

(1,000 meters) x (1 second / 331.3 meters) = 3.018 seconds .

All of the earth's life and weather exists within the stratosphere.
a. True
b. False

Answers

The statement “All of the earth's life and weather exists within the stratosphere” is absolutely false. Thus, the correct option for this question is B.

What is Stratosphere?

Stratosphere may be defined as the second layer of the atmosphere as you go upward. It is the layer of the earth's atmosphere above the troposphere. Apart from this, it significantly extends to about 50 km above the earth's surface.

According to the context of this question, the correct and absolute answer is the troposphere. It is the first layer that is where we are able to do most of our activities. This is where we can see the formation of clouds, and the production of rain, hail, snow, and other weather phenomenon.

The troposphere is essential as it contains the Earth's weather as well as greenhouse gases to maintain the temperature on Earth. The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.

Therefore, the statement “All of the earth's life and weather exists within the stratosphere” is absolutely false. Thus, the correct option for this question is B.

The statement “All of the earth's life and weather exists within the stratosphere” is false. The answer is letter B. The answer is the troposphere. The first layer, troposphere, is where we are able to do most of our activities. This is where we can see the formation of clouds, the production of rain, hail, snow and other weather phenomenon. Also, this layer is where the greatest amount of air pressure because most of the molecules of air are in this area. Like us, air has also mass and the pressure is brought down by the earth’s gravity causing an increase in weight exerted on you as you descend lower into the atmosphere. So, as you enter into the other layers of atmosphere above the troposphere, the air pressure starts to decrease. Below the atmosphere is the hydrosphere. This is where all liquid forms are located. And since the seawater has a greater mass than air, it has the greatest pressure.
