KSU BIOLOGY 198 EXAM 2 QUESTIONS
WITH DETAILED ANSWERS
, Ecology - ANSWERThe study of interactions between life forms and their environment.
Ecosystem - ANSWERAll living organisms in an environment plus the physical and
chemical environments in which they live.
GPP (Gross Primary Productivity) - ANSWERAll the sunlight that hits a given area,
primary producers use it to grow and reproduce, then converted to NPP
NPP - ANSWERThe usable energy left over for consumers is called ____. It helps
determine how many trophic levels an ecosystem can hold.
Entropy - ANSWERRandomness
Second - ANSWER______ Law of Thermodynamics: as energy is passed on
(converted) some is lost as heat. This increases entropy.
Nutrients - ANSWERWhat is cycled in biogeochemical cycles?
Nutrients - ANSWER_______ could not cycle if energy was not present.
Autotroph - ANSWERA _______ is a producer, meaning it makes its own "food" by
converting energy into a usable form for the consumers to use. Nutrients could not cycle
without this energy flow.
Heterotroph - ANSWERA ________ is a consumer. If it didn't consume producers, no
nutrients would be passed on.
Producer - ANSWERAn organism that makes its own food.
Decomposer - ANSWERAn organism that breaks down dead and decaying organisms.
Consumer - ANSWERAn organism that eats other organisms to gain energy.
Trophic - ANSWERA ______ level groups organisms into how much energy is available
to them and how much they have.
Food Chain - ANSWERThe linear relationships of feeding.
Food Web - ANSWERAll relationships in regard to eating habits. Includes
decomposers.
rainforest - ANSWERWhat biome has the highest NPP?
