NR 103 Exam 4 Questions With Complete Solutions
"naturalized" speciesintroduced species continues to be part of a
new ecosystem over time Correct Answers "naturalized"
species
(Elizabeth Kolbert)
deep sea vents as future ocean study points
-survey study
- give gradient of CO2 (tipping points)
- have been spewing CO2 for 100+yrs
(Findings: less species/less diversity) Correct Answers the sea
around us
4 major carbon pools Correct Answers atmosphere
land
ocean
sediment/rocks
a graph which plots the ongoing change in concentration of
carbon dioxide in Earth's atmosphere since 1958 Correct
Answers keeling curve
big fierce animals are rare Correct Answers they require more
energy
biological legacies Correct Answers organism or remains of
organism that persist after a disturbance and are incorporated
into the recovering ecosystem
biologically derived by fixation
, (rhizobia bacteria) Correct Answers nitrogen
biomass Correct Answers mass or organism per unit area
biotic homogenization Correct Answers Refers to the gradual
replacement of native biotas by locally expanding non-natives,
is a global process that diminishes floral and faunal distinctions
among regions
biotic resistance hypothesis Correct Answers ecosystems with
high biodiversity are more resistant against invaders than
ecosystems with low biodiversity
carbon Correct Answers lifes building block
photosynthetic carbon uptake fuels most biotic processes
essential part of organic molecules
living tissue is composed primarily of Carbon
index of biosphere health
Carbon Inputs Correct Answers photosynthesis by plants
provides the carbon and energy that drive most biological
processes in ecosystems
carbon move through uptake/release by organisms and chemical
reactions
uptake greater in cold release greater in warm
photosynthetic organisms die (surface carbon or to mid/deep
pool) Correct Answers oceans sinks
carbon pools Correct Answers fossil carbon, oceans, soils,
atmosphere, plants
