the ability to bring about change or to do work

the study of energy

the total amount of energy in the universe is constant and conserved (cannot be created or destroyed), there always has been and always will be the exact same amount of energy in the universe

• the first law of thermodynamics

• the second law of thermodynamics

energy can be transformed from one type to another or transferred from one place to another, and energy is lost to the surroundings in the process, so sustaining energy in a system, requires inputs of energy, the transfers and transformations of energy through biological systems maintain order and life

• first law of thermodynamics

• second law of thermodynamics

Energy exists in many forms in the universe:

• heat

• light

• chemical

• kinetic

• potential

a form of potential energy defined as the energy stored in the bonds between atoms in a molecule

The source of energy for living organisms is the _________ even though not all organisms can use the light energy from the ________, which then is turned into food through transformations because all organisms use this type of chemical energy

• moon

• ocean

• sun

• tides

True or False: Energy is not made of anything, so it does not have mass. Rather, energy is stored within the bonds between atoms in matter

• false

• True

 anything that has mass and takes up space

matter cannot be created or destroyed, but it can be transformed from one state to another (solid, liquid, gas). Therefore, atoms cannot be created or destroyed but can be rearranged to form different molecules

• the law of conservation of space

• the law of conservation of matter

• the law of conservation of energy

• the law of conservation of mass
