What is a transfer of energy through organisms?

A transfer of energy through organisms is known as an energy flow. It involves the movement of energy from one organism to another as food is consumed and digested. This process is crucial for sustaining life within an ecosystem.

Is a river potential or kinetic energy?

Both, if you refer to a flowing stream. The topographic elevation of the streambed above the base level toward which it leads (e.g., sea level) is indicative of the potential energy of the water in the river. (Another kind of potential energy is proportional to the water depth above the streambed.) The river's kinetic energy is proportional to the square of its current velocity and to the mass of moving water. Remember KE = (m v^2)/2 from physics?

If the river ceases to flow, for example enters a lake or impoundment, its kinetic energy will decrease to zero. Yet because of potential energy, its water may still have considerable energy.

What is the force that acts on rock to change its shape?

The force that acts on rock to change its shape is typically stress, which can come from tectonic forces, such as compression, tension, or shear. These stresses can cause the rock to deform, leading to changes in its shape and structure over time.

Why is the sun is the primary source of energy in the ecosystem?

Because it is the main source for all plant life. Thus effecting the rest of the ecosystem. It is the main source for plant life because it is how photosynthesis happens. Without photosynthesis there would be no food for the plants. No energy in the plants and no energy or nutrients to pass along the chain.

(Basically:::: Because plants would die without photosynthesis (from the sun) and so would everything else, because it is all connected.)

Answers for True or False Viscosity is the tendency of a fluid to resist flow Both gases and liquids can display viscosity?

True. Viscosity is indeed the tendency of a fluid to resist flow. Both gases and liquids can exhibit viscosity, with liquids typically displaying more noticeable viscosity compared to gases due to the closer proximity of their particles.

What is the major energy resource for earth?

The major energy resource for Earth is the Sun. Solar energy is harnessed through technologies like solar panels to generate electricity and power various applications. It provides a clean and renewable source of energy for our planet.

What is the most abundant source of energy in the Earth?

The most abundant source of energy on Earth is solar energy. The Sun continuously radiates vast amounts of energy, which can be harnessed through technologies such as solar panels to generate electricity and heat for various applications.

What causes more thunder to be happen in a place?

More thunder is likely to occur in a place when there is a higher concentration of charged particles in the atmosphere, typically caused by strong updrafts associated with thunderstorm development. Additionally, the presence of tall structures or geographic features can lead to more lightning strikes and hence more thunder.

What is a description of the energy flow through an ecosystem?

The plants get 10 percent energy from the sun. The highest concentration of energy is in producers [for example plants or algae].

Then the primary consumer eats only plants but retain only ten percent of their energy.

Secondary consumers eat the primary consumers and get ten percent from the primary consumers. Secondary consumers can also eat plants. Then the final level is the tertiary consumers who are typically carnivores and eat secondary consumers. They retain 10 percent from the secondary consumers. So with each level less energy is achieved.

How does moss get energy?

Moss obtains energy through photosynthesis, a process in which they use sunlight to convert carbon dioxide and water into glucose and oxygen. They also absorb water and nutrients directly from their surrounding environment through their leaves and stems.

Why are natural resources in danger of being used up?

I think you have to qualify this, not all the earth's resources are running out. As far as I know there is still plenty of coal and iron ore, two of the most important. Uranium is still expected to last to the end of this century at least. Natural gas may be running out in the best places to get it from, but as a whole the earth still has plenty available. If it has to be brought to North America and Europe either by refrigerated tanker, or in long pipelines from Russia, it is going to be more expensive, but it is still available. Oil production seems to be the most likely to be in short supply. This is partly because the easy deposits have been depleted, also because demand in China and India is increasing.

Basically, I think it is too early to say the resources are running out, but they will at some time in the future. The reason is that new deposits are not being created, or not at any useful rate. It took millions of years for the deposits we have now to form, and we are using them up at an unsustainable rate. Man will have to develop new technology to overcome this, such as nuclear fusion and renewable energy. There is an almost limitless supply of deuterium in water. Also the winds are not going to stop blowing, or the sun from shining.

How are most living things produced?

Most living things are produced through reproduction, where individuals pass on their genetic material to produce offspring. This can occur through sexual reproduction, where genetic material from two parents combines, or asexual reproduction, where genetic material is copied from a single parent.

Why is Earths surface heated unevenly even though the suns energy output is mostly constant?

The Earth's rotation cause one side to be heated while the other side cools, cloud forming evaporation causes certain areas to be shaded and cooler while others get direct sunlight. Different surface colors and textures reflect or absorb the sun's heat at different rates. This causes winds that move warmer air to cooler areas. At each latitude the sun's rays hit the Earth with a different angle of incidence. The tilt of the Earth's rotational axis produces seasonal variations.

There are a great many things that aren't constant even if solar output is somewhat constant.

Which device converts electric energy into rotational kinetic energy?

An electric motor is the device that converts electric energy into rotational kinetic energy. It works by using magnetic fields to generate a rotational force, which causes a shaft to rotate and perform mechanical work.

A object has one joule of potential energy explain what does it means?

We know that energy is defined as the ability to do work.So an object has one joule of potential energy means that the body has capability to do a work of one joule.

We may say that the object with 1 joule of potential energy is the force field and our work is stored in displacing the object against the field

Name the four stages of primary succession?

The four stages of primary succession are: 1) Pioneer stage, where bare rock or soil is colonized by lichens and mosses; 2) Seral stage, where small plants like grasses and herbs begin to establish; 3) Transitional stage, where shrubs and small trees start to grow; 4) Climax stage, where a mature ecosystem with a stable community of plants and animals is formed.

What are five primary energy sources?

the sun is the main source of energy for earth but indirectly as by solar energy the plants do photosynthesis which powers the planet earth . you may find detailed info in the book "eating the sun by oliver morton"

What type of energy can be generated in volcanic areas?

Geothermal energy can be generated in volcanic areas. This type of energy harnesses heat produced by the Earth's molten core to generate electricity through geothermal power plants. Volcanic areas provide access to high temperatures and steam, making them ideal locations for geothermal energy production.

What does the term radiation mean?

Radiation is a term used for any energy or energetic particles that flow out from a source of energy or energetic particles.

Your body when in an area colder than 98.6 degrees, F, radiates infrared energy. (Heat).

Which energy source uses heat from underground?

Geothermal energy uses heat from underground to generate power. This renewable energy source relies on the heat stored beneath the Earth's surface to drive turbines and produce electricity.

Why does paper dipped in water makes less sound than the paper which is not dipped in water when teared?

When paper is dipped in water, it absorbs moisture, making it more flexible and less rigid. This allows the paper fibers to stretch and bend before breaking, which reduces the noise generated when torn. Dry paper, on the other hand, is stiffer and more brittle, leading to a louder tearing sound.

Describe the two methods euglenophytes can use to obtain energy?

Euglenophytes obtain energy through photosynthesis, where they use chlorophyll to convert light energy into chemical energy. They can also feed on organic matter in their environment through a process called phagocytosis, allowing them to absorb nutrients and obtain energy from other organisms.

What is a living thing that provides energy for a virus?

A virus is a parasite that relies on a host cell for energy. It cannot produce its own energy and instead hijacks the metabolic processes of the host cell to replicate itself.
