SCIENCE 7B LESSON 1

IS THE ABILITY TO CAUSE A CHANGE IN A SYSTEM.

CHANGE OF ONE TYPE OF ENERGY INTO ANOTHER FORM(S) OF ENERGY

A PUSH OR A PULL ON AN OBJECT THAT CAUSES THE OBJECT TO START MOVING, STOP MOVING, OR CHANGE DIRECTION.

IS THE TRANSFER OF ENERGY TO AN OBJECT, CAUSED BY A FORCE TO MOVE AN OBJECT IN THE DIRECTION OF THAT FORCE.

the force that attracts all objects in the universe to one another.

amount of force exerted on a given area.

is caused by the pressure in the plant cell due to the force of water inside the cell pushing on the cell membrane and in turn pushing on the cell wall

The energy of motion in an object or organism

is the energy that an object or organism has due to its position, condition, or chemical composition

energy stored within the bonds of a molecule.

energy that results from the position or motion of charged particles.

is another form of kinetic energy, the vibration of particles generates sound energy.

is the total amount of kinetic energy of all the molecules in an organism.

Is a community of living organisms and their nonliving environment

is the place where an organism lives within an ecosystem For example: a snail’s habitat could be a stream in the forest

a producer are called an autotroph, uses energy to make food. Most producers use sunlight to produce food (photosynthesis)

an organism that gets energy and nutrients by breaking down the remains of other organisms. For example, fungi such as mushrooms, and some bacteria

is an organism that eats other organisms

a consumer that eats only plants For Example, bison, grasshoppers

Eats other animals For Example badger or wolf

eats both plants and animals For Example Humans

is a specialized consumer who feeds on dead organisms For example Vultures.

is the path of energy transfer from producers to consumers.

shows the feeding relationships among many different organism in and ecosystem
