Unit 4: Matter and Energy In Ecosystem
Producer
A living that can make its own energy storage molecules.
energy storage molecule
A molecule that organisms can use to release the energy needed to survive
Biodome
a closed ecosystem made by humans
Carbon
a type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecule
Ecosystem
all the living and nonliving things interacting in a particular area
Decomposer
an organism (fungi, bacteria, worms) that gets energy storage molecules (such as glucose) by breaking down dead matter.
Organisms
living things, such as plants, animals, and bacteria
Biotic Matter
matter that makes up the living and dead organisms in an ecosystem.
Abiotic Matter
matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks
Consumer
organism that needs to eat in order to get energy storage molecules.
System
set of interacting parts forming a complex whole
Input
something that is required for a process
Output
something that results from a process
Cellular Respiration
the chemical reaction between oxygen and glucose that releases energy into cells
Photosynthesis
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)
Carbon Dioxide
a molecule made of carbon and oxygen atoms.
Chloroplast
A green organelle found in plant cells where photosynthesis occurs.
Cell
Basic unit of life
dead matter
biotic matter that is now dead like fallen leaves or dead animals
Molecule
group of atoms joined together in a particular way
