  • What happens to the excess sugar made by plants during photosynthesis?
    It is stored as starch in leaves, roots, flowers, seeds or stems of a plant for later use.
  • True or False: Energy can be destroyed.
    False. It can only be converted from one form to another.
  • How do animals get their energy?
    From the food they eat. Some animals eat plants while others eat other animals.
  • Where might elastic potential energy be stored?
    In a stretched rubber band or compressed spring
  • What is the main energy conversion for a microphone?
    Electrical energy → sound energy
  • The major energy source in the world is
    The sun
  • How do plants get light energy for use in photosynthesis?
    The leaves have chloroplasts which contain chlorophyll to trap light from the sun and converts it into chemical energy.
  • What is the main energy transfer for a long-distance runner?
    Chemical energy → kinetic energy
  • What is the main energy conversion for an apple falling from a tree?
    Gravitational potential energy → kinetic energy
  • What do wind and moving water have in common?
    They both have kinetic energy
  • These are the tiny openings on the leaves that allow a plant to take in carbon dioxide, which is needed for photosynthesis.
    stomata
  • The ability to do work is called
    energy
  • What is the name of the energy stored by a moving object?
    Kinetic energy
  • ___________ is the process in which light energy is converted to chemical energy in the form of sugars.
    Photosynthesis
  • Which form of energy does a plant store when light is transformed during photosynthesis into sugars?
    chemical potential energy
  • When energy transformation occurs, what form of energy is always produced?
    Heat
