Matter and energy in ecosystems
biodome
a closed ecosystem made by humans
molecule
a group of atoms joined together in a particular way
carbon dioxide
a molecule made of carbon and oxygen atoms
glucose
a molecule that organisms can use to release energy, that is made of carbon, hydrogen, and oxygen molecules
energy storage molecules
a molecule that organisms can use to release the energy they need to survive
system
a set of interacting parts forming a complex whole
reactant
a starting substance that is part of a chemical reaction
carbon
a type of atom(a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules
glycogen
a type of energy storage moelcule
fat
a type of energy storage molecule
starch
a type of energy storage molecule made of many glucose molecules connected together
ecosystem
all the living and nonliving things in a particular area
product
an ending substance that is made during a chemical reaction
producer
an organism that an make its own energy storage molecules(such as glucose)
decomposer
an organism that gets energy storage molecules(such as glucose) by breaking down dead matter
consumer
an organism that needs to eat in order to get energy storage molecules(such as starch and fat)
organisms
living things, such as plants, animals, and bacteria
abiotic matter
matter that make up the non-living parts of an exocystem, such as air, water, and rocks
biotic matter
matter that makes up the living and dead organisms in an ecosystem
input
something that is required for a process
output
something that results from a process
energy
the ability to make things move or change
mitochondria
the part of a cell where cellular respiration happens
chloroplasts
the part of a cell where photosynthesis happens
atoms
the tiny pieces that all matter—all the stuff in the world—is made of
connect
to link two or more things
photosynthesis
the process which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose(an energy storage molecule)
