NR 2030 EXAM 3 |QUESTIONS AND 100%
CORRECT AND WELL DETAILED
succession - ANSWER species composition of communities change over time
mechanisms of change - ANSWER colonization and extinction
henry cowles - ANSWER developed the concept of succession in the 1880s when
he studied succession on sand dunes around the shores of Lake Michigan
Frederic Clements - ANSWER "Climax State" concept that emphasized the
predictable aspects of community structure following succession.
Henry Gleason - ANSWER maintained that each species responds independently
to its own limiting factors
ecosystem - ANSWER all of the components of an ecological system, biotic and
abiotic, that influence the flow of energy and elements.
energy in ecosystems - ANSWER originates with primary production by
autotrophs.
gross primary productivity - ANSWER the amount of carbon fixed by the
autotrophs in an ecosystem over a period of time
net primary productivity - ANSWER GPP- respiration
-allocated to plant growth, reproduction, storage, and consumption by herbivores and
detritivores
-plants allocate the most growth to capture of limiting resources
, remote sensing - ANSWER reflection of solar radiation to estimate chlorophyll
concentration.
Minirhizotrons - ANSWER allow researchers to observe the dynamics of root
growth and death belowground.
how npp is constrained - ANSWER precipitation, temperature, nutrients,
herbivory
Nutrients - ANSWER Substances in food that your body needs to grow, to repair
itself, and to supply you with energy
Biogeochemistry - ANSWER The study of the physical, chemical, and biological
factors that influence the movements and transformations of chemical elements.
major nutrients in the biosphere? - ANSWER carbon, hydrogen, oxygen, nitrogen,
phosphorous, sulfur
Nitrogenase - ANSWER an enzyme of nitrogen-fixing microorganisms that
catalyzes the conversion of nitrogen to ammonia to break down N2 so it is usable
for plants.
nutrient pool - ANSWER site of storage
nutrient flux - ANSWER amount moved from one pool to another
phosphorous - ANSWER soil is the ultimate source of phosphorous for plants
