100

matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks

Abiotic Matter

100

an organism that needs to eat in order to get energy storage molecules (such as starch and fat)

Consumer

100

all the living and nonliving things interacting in a particular area

Ecosystem

100

when two or more populations use the same resource, such as the same food source 


competition

100

what are living things, such as plants, animals, and bacteria called? 

organisms

200

the chemical reaction between oxygen and glucose that releases energy into cells

Cellular Respiration

200

an organism that gets energy storage molecules (such as glucose) by breaking down dead matter

decomposer

200

a molecule that organisms can use to release the energy they need to survive

Energy Storage Molecule

200

a scientist who studies the interactions of organisms with each other and their environment

ecologist

200

 the amount of matter that makes up an object

Mass

300

a type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules

Carbon

300

the part of a cell where photosynthesis happens

Chloroplast

300

a molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms

Glucose

300

the energy that an object has because it is moving

Kinetic Energy

300

formula to detetermine change of temperature in thermal energy

Q=MCΔT 

400

 the tiny pieces that all matter—all the stuff in the world—is made of

Atoms

400

a molecule made of carbon and oxygen atoms

Carbon Dioxide

400

an ending substance that is made during a chemical reaction

Product

400

population that is eaten by organisms from another population

resource population

400

 to move from one object to another or one place to another

transfer

500

matter that makes up the living and dead organisms in an ecosystem

Biotic Matter

500

a starting substance that is part of a chemical reaction

Reactant

500

the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose (an energy storage molecule)

Photosynthesis

500

living things, such as plants, animals, and bacteria

organisms

500

energy that is transferred to heat

Thermal Energy
