Matter and Energy in Ecosystems
matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks
Abiotic Matter
an organism that needs to eat in order to get energy storage molecules (such as starch and fat)
Consumer
all the living and nonliving things interacting in a particular area
Ecosystem
a result or change that happens because of an event or process
Effect
a push or a pull that can change the motion of an object
Force
the chemical reaction between oxygen and glucose that releases energy into cells
Cellular Respiration
an organism that gets energy storage molecules (such as glucose) by breaking down dead matter
decomposer
a molecule that organisms can use to release the energy they need to survive
Energy Storage Molecule
an event or process that leads to a result or change
Cause
the amount of matter that makes up an object
Mass
a type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules
Carbon
the part of a cell where photosynthesis happens
Chloroplast
a molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms
Glucose
the energy that an object has because it is moving
Kinetic Energy
anything that has mass and takes up space
Matter
the tiny pieces that all matter—all the stuff in the world—is made of
Atoms
a molecule made of carbon and oxygen atoms
Carbon Dioxide
an ending substance that is made during a chemical reaction
Product
a force between an object and the surface it is moving over
Friction
speed in a particular direction
Velocity
matter that makes up the living and dead organisms in an ecosystem
Biotic Matter
a starting substance that is part of a chemical reaction
Reactant
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
how fast an object is moving
Speed
to reach a conclusion using evidence and reasoning
