What do you know about Energy?

What is the role of energy in ecosystems?

• Energy is created by producers and consumed by consumers.

• Energy flows through ecosystems, starting from the Sun, to producers (plants), and then to consumers (animals), supporting life processes.

• Energy is stored in the soil and released during decomposition.

• Energy is only used by plants and not by animals.

What is the relationship between temperature and sound travel?

• Sound travels faster in colder air than in warmer air.

• Sound travels at the same speed regardless of temperature.

• Sound travels faster in warmer air than in colder air because warmer air has more energy.

• Temperature has no effect on sound travel.

What is energy?

• Energy is the ability to do work or cause change.

• Energy is a measure of temperature.

• Energy is the total amount of matter in an object.

• Energy is the force applied to an object.

What is renewable energy?

• Energy that comes from fossil fuels

• Energy that can be replenished naturally, such as solar, wind, and hydroelectric power

• Energy that is only available during the day

• Energy that is produced by nuclear reactions

What is the law of conservation of energy?

• Energy can be created and destroyed.

• Energy can only be transformed from one form to another.

• Energy is a finite resource that can be depleted.

• Energy can be converted into matter.

What is the primary source of light energy on Earth?

• The Moon

• The Sun

• Artificial lights

• Stars

What is light energy?

• Light energy is a form of electromagnetic radiation that is visible to the human eye.

• Light energy is a type of sound energy produced by vibrating objects.

• Light energy is a form of kinetic energy generated by moving objects.

• Light energy is a type of thermal energy that heats up materials.

What is non-renewable energy?

• Energy that comes from sources that can be replenished quickly, such as solar and wind power.

• Energy derived from sources that cannot be replenished in a short period, like fossil fuels such as coal, oil, and natural gas.

• Energy that is produced from nuclear reactions and is considered renewable.

• Energy that is generated from geothermal sources and is sustainable.

How does sound travel through different mediums?

• Sound travels fastest through gases, slower through liquids, and slowest through solids.

• Sound travels at the same speed through all mediums regardless of their state.

• Sound travels fastest through solids, slower through liquids, and slowest through gases.

• Sound travels fastest through liquids, slower through solids, and slowest through gases.

What is kinetic energy?

• Kinetic energy is the energy of an object at rest.

• Kinetic energy is the energy of an object in motion.

• Kinetic energy is the energy stored in an object due to its position.

• Kinetic energy is the energy released during a chemical reaction.
