The ability to do work is called
energy
The major energy source in the world is
The sun
___________ 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
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.
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.
How do animals get their energy?
From the food they eat. Some animals eat plants while others eat other animals.
These are the tiny openings on the leaves that allow a plant to take in carbon dioxide, which is needed for photosynthesis.
stomata
What is the name of the energy stored by a moving object?
Kinetic energy
Where might elastic potential energy be stored?
In a stretched rubber band or compressed spring
What is the main energy conversion for an apple falling from a tree?
Gravitational potential energy → kinetic energy
True or False: Energy can be destroyed.
False. It can only be converted from one form to another.
What is the main energy transfer for a long-distance runner?
Chemical energy → kinetic energy
What is the main energy conversion for a microphone?
Electrical energy → sound energy
When energy transformation occurs, what form of energy is always produced?
Heat
What do wind and moving water have in common?
They both have kinetic energy
