abiotic matter
matter that makes up the nonliving parts of an ecosystem
biotic matter
matter that makes up the living and dead organisms in an ecosystem
carbon
a type of atom that makes up molecules such as carbon dioxide and energy
carbon dioxide
a molecule made of carbon and oxygen atoms
carbon cycle
the movement of carbon from the nonliving environment into living things and back
cellular respiration
the chemical reaction between oxygen and glucose that releases energy into cells
cellular respiration equation
C6H12O6+6O2---> 6CO2+6H2O+ATP
chloroplast
the part of a cell where photosynthesis happens
consumer
an organism that needs to eat in order to get energy storage molecules (such as glucose)
decomposer
an organism that gets energy storage molecules (such as glucose) by breaking down dead matter
ecosystem
all the living and nonliving things interacting in a particular area
energy
the ability to make things move or change
energy storage molecule
a molecule that organisms can use to release the energy they need to survive
glucose
a molecule that organisms can use to release energy
input
something that is required for a process
mitochondrion
the part of a cell where cellular respiration happens
molecule
a group atoms joined together in a particular way
organisms
living things, such as plants, animals, fungus, protists, archaea, and bacteria
organisms that perform photosynthesis
plants, algae, and some bacteria
output
something that results from a process
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)
Photosynthesis equation
6CO2 + 6H2O ------> C6H12O6 + 6O2
producer
an organism that can make its own energy storage molecules (such as glucose)
product
an ending substance that is made during a chemical reaction
reactant
a starting substance that is part of a chemical reaction
system
a set of interacting parts forming a complex whole
