Which statement best describes what happens to energy and matter in a system?
Which statement best describes energy and matter in a closed system? Energy can flow into and out of the system but matter cannot.
Which statement about matter and energy agrees with the First Law of Thermodynamics?
Which statement about matter and energy agrees with the first law of thermodynamics? Matter and energy cannot be created or destroyed, but can change from one form to another.
How does energy move through living things?
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
How is the movement of energy and matter similar?
What are the Similarities Between Energy Flow and Matter Cycling? Both energy and matter flow through food chains in an ecosystem. They are important in order to keep the ecosystem balanced. Living organisms need both matter and energy.
Which statement best describes the kinetic energy theory of matter?
Which of the following statements is the best description of the kinetic theory of matter? Matter is made up of atoms, which are in constant motion and have energy.
What does the first law of thermodynamics state about energy?
The first law of thermodynamics states that energy can neither be created nor destroyed, only altered in form. For any system, energy transfer is associated with mass crossing the control boundary, external work, or heat transfer across the boundary. These produce a change of stored energy within the control volume.
Which way does energy flow?
A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem.
Which describes the possible flow of energy in an ecosystem?
A food chain describes the passage of energy between trophic levels. A food web is a set of interconnected and overlapping food chains. Food webs are interconnected, such as nearby land and a marine food webs.
What is the movement of energy?
Energy flow is the flow of energy through living things within an ecosystem. All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain.
What is the movement of energy called?
Motion Energy Motion Energy is the movement of objects and substances from one place to another. Objects and substances move when a force is applied according to Newton's Laws of Motion. Wind is an example of motion energy. Sound is the movement of energy through substances in longitudinal (compression/rarefaction) waves.
Which of the following best describes kinetic energy?
Q. Which best describes "kinetic energy?" The energy an object has due to being in motion.
Which of the following best describes potential energy?
Which of the following best defines potential energy? a) Potential energy is energy that cannot be converted to kinetic energy.
What does the first law of thermodynamics state about energy quizlet?
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.
Which of the following statements best describe the first law of thermodynamics?
The correct answer to the above question is: a) Energy cannot be created or destroyed.
How does energy move through systems?
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
How does energy move through the body?
The energy flows through these twelve regular meridian channels in the following rhythm: From the chest area via the three arm Yin channels – lung, pericardium, heart – to the hands. From here we connect with the three paired arm Yang channels – large intestine, San Jiao, small intestine – and flow up to the head.
What is the flow of energy called?
The energy flow is the amount of energy that moves along the food chain. This energy flow is also known as calorific flow.
How does energy flow in an ecosystem quizlet?
In an ecosystem, energy flows from producers (plants) to primary consumers (herbivores) to secondary and tertiary consumers (carnivores). Food chains and food webs model this energy flow and these feeding relationships. Each step in a food chain is called a trophic level.
Which of the following correctly describes how energy moves through living systems?
So, the correct answer is 'Energy flows while matter is cycled'.
What is the movement of energy from one object to another?
A common example of energy transfer that we see in everyday life is the transfer of kinetic energy—the energy associated with motion—from one moving object to a stationary object via work. In physics, work is a measure of energy transfer and refers to the force applied by an object over a distance.
What is the best definition of energy?
energy. ( ĕn′ər-jē ) The capacity or power to do work, such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another.
Which statements describes potential energy?
Potential energy can be described as the energy stored in an object that is at rest, and that could be used to accomplish some task. Kinetic energy is the energy of an object in motion. A boulder at the top of a cliff has potential energy that is converted into kinetic energy when it starts to roll downhill.
Which of the following best describes energy?
Energy is the ability of an object to do work.
What is it called when energy is moving?
The energy associated with an object's motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy.
What is the energy in motion?
Kinetic energy is the energy of motion.
How does the first law of thermodynamics explain how energy moves through an ecosystem?
The first law of thermodynamics states that energy cannot be created or destroyed, only transformed; Energy enters an ecosystem as solar radiation, is conserved, and is lost from organisms as heat. cannot be created or destroyed; Chemical elements are continually recycled within ecosystems.
Which of the following statements describes what occurs with energy as a result of the law of conservation of energy?
Which of the following statements describes what occurs with energy as a result of the Law of Conservation of Energy? The amount of energy before a process occurs is less than the energy after the process occurs.
Which of the following statements best describes a primary mechanism by which the energy?
Which of the following statements best describes a primary mechanism by which the energy released in ATP hydrolysis is used directly to drive endergonic chemical reactions in a cell? The released phosphate is used to form phosphorylated intermediates that are more reactive than the original unphosphorylated substrate.
How does energy move between living things?
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
Does energy flow up or down?
Also, when you stand up, energy generally travels upwards toward your head. When you sit down, your energy flows down towards your feet. The movement of our vital energy is also connected with the breath. As you inhale the energy is drawn upwards and as you exhale energy flows downward.
