If the primary source of atmospheric thermal energy on Earth is energy from the Sun what conclusion can be made from the diagram?

The diagram likely shows the process of solar radiation heating the Earth's surface, which in turn drives convection and other atmospheric processes. This illustrates the important role the Sun plays in heating the Earth's atmosphere and driving weather patterns.

Is Every time energy is transferred between organisms in a food web some of the energy is lost as heat.?

Yes, energy is lost as heat each time it is transferred between organisms in a food web. This is due to inefficiencies in energy transfer, metabolism, and body heat generation. The second law of thermodynamics states that energy transformations are never 100% efficient, leading to energy loss in the form of heat.

A mitochondrion is having a problem creating enough energy to build new molecules which problem most likely exists with the mitochondrian?

The problem most likely exists within the electron transport chain of the mitochondrion. This chain is responsible for generating the majority of ATP, the cell's energy currency. Issues such as a lack of substrates, damage to protein complexes, or inhibition of enzyme activity within the electron transport chain could lead to a decrease in energy production.

The sequence of eating relationship or energy transfer among organisms?

The sequence of energy transfer among organisms is known as a food chain. It starts with producers (plants) capturing energy from the sun through photosynthesis, which is then consumed by primary consumers (herbivores), followed by secondary consumers (carnivores) that eat the primary consumers, and so on. This flow of energy through the food chain is essential for maintaining balance in ecosystems.

What is the main source of energy for most processes at Earth?

The main source of energy for most processes on Earth is the Sun. Solar energy is absorbed by plants through photosynthesis, providing energy for the food chain and powering various natural phenomena such as weather patterns and ocean currents.

How do fungi obtain energy?

Fungi obtain energy by breaking down organic matter through the process of decomposition. They secrete enzymes to break down complex organic compounds into simpler molecules, which they then absorb and use as a source of energy. Fungi can also form symbiotic relationships with plants where they help in nutrient absorption in exchange for sugars produced by the plants through photosynthesis.

What atom has one valence electron?

hydrogen and the alkali metals lithium, sodium, potassium, rubidium, cesium, and francium all have one valence electron.

How does thermophiles get energy?

Thermophiles get energy by converting organic or inorganic compounds into usable energy through chemical processes like oxidation or fermentation. They are capable of withstanding high temperatures and thrive in extreme environments like hot springs and hydrothermal vents.

The steps by which energy flows among a group oforganisms is called a what?

The steps by which energy flows among a group of organisms is called a food chain. This represents the transfer of energy from one organism to another as they consume each other.

Why are wind hydroeletric and geothermal energy resources not suitable for providing energy worldwide?

I think they are VERY suitable; but so far, government policies don't exactly favor renewable and clean energy options. That is, billions are given in subsidies to petrol companies, money which would really be better invested in clean energy options.

Why do we say geothermal energy is not sustainable?

Geothermal energy is considered sustainable because it is a renewable energy source that relies on heat from the Earth's crust. However, some concerns about sustainability include the potential for depleting local heat reservoirs if not managed properly and the release of greenhouse gases and other pollutants during the extraction and conversion processes. It is important to conduct thorough monitoring and consider environmental impacts to ensure the long-term sustainability of geothermal energy.

What is the source of energy that drives the movement of the lithospheric platesWhat is the source of energy that drives the movement of the lithospheric plates?

The source of energy that drives the movement of the lithospheric plates is believed to be the heat generated by radioactive decay in the Earth's interior, primarily in the mantle. This heat creates convection currents that cause the plates to move over the semi-fluid asthenosphere beneath them.

Where does a skater have the most kinetic energy?

At rest at top of slope, it is all potential energy(mass * g * vertical distance to bottom of slope). Ignoring friction losses, this will translate to all kinetic energy at the bottom. kinetic energy = 0.5 * mass * velocity squared

example:

mass of sled + rider = 100 kg

g = 9.82 ((m/s)/s) acceleration due to gravity

vertical distance = 20 metres

so:

potential energy at slope top = 100 * 9.82 * 20 = 19 640 joules

so:

kinetic energy at bottom = 19 640 joules

so :

19 640 = 0.5 * 100 * velocity ^2

so:

velocity = square root (19 640 / (0.5 * 100))

velocity = 19.82 metres / sec

The movement of enery and nutrients through living systems are different because energy flows in a?

Energy flows in a one-way direction through living systems, entering as sunlight and being transformed into chemical energy by primary producers through photosynthesis. Nutrients, on the other hand, are recycled within ecosystems through the biogeochemical cycles, moving between living organisms and the abiotic environment in a continuous loop.
