 Definition
"energy currency"
Term
adenosine diphosphate
 Definition
energy is stored as chemical energy by convering a relating but lower-energy molecule
Term
photosynthesis
 Definition
algae, plants, and some other organisms capture the sun's energy and use it to make glucose.
Term
photosynthetic pigments
 Definition
photosynthesis begins when solar energy, in the form of sunlight, is absorbed by chemicals with an organism called.
Term
chlorophyll
 Definition
the most common photosynthetic pigment
Term
carbon dioxide
 Definition
combines with water to help make glucose
Term
carbon fixation
 Definition
when photosynthesis converts carbon from an inorganic compound to a organic compound
Term
oxygen gas
 Definition
the product of photosynthesis
Term
autotrophs
 Definition
obtain all the energy they need from sunlight and don't need to eat
Term
heterotrophs
 Definition
organisms that cannot produce their own food and must obtain energy from organic matter that was produced by autotrophs
Term
respiration
 Definition
performed to use the solar energy stored in organic chemicals by photosynthesis
Term
aerobic
 Definition
the chemical reactions are different, but the net result of oxygen-dependent, respiration is esentially the reverse of photosynthesis.
Term
anaerobic
 Definition
used if oxygen isnt available
Term
primary production
 Definition
when autotrophs produce more organic matter than they use respiration, there is a net increase in organic matter
Term
primary producers
 Definition
organisms that perform primary production of food
Term
nutrients
 Definition
raw materials
Term
nitrate (NO3-1)
 Definition
is the most mportant form of nitrogen in the ocean
