QUESTIONS & ANSWERS 100%
SOLVED
The biotic components of terrestrial ecosystems are referred to as -
ANSWERBiomes
Biomes - ANSWERgroupings of plants and animals (communities) defined by a
dominant vegetation type
Two abiotic factors - ANSWERClimate
Weather
Climate - ANSWERprevailing, long-term weather conditions found in the area
Weather - ANSWERspecific, short-term weather atmospheric conditions of
temperature, moisture, sunlight, and wind
What is the taxonomic grouping of humans / primates / great apes primarily -
ANSWERfamily Hominidae / Humans thought to be closely related to bonobos
(pigmy chimps)
Net Primary Productivity (NPP) - ANSWERthe total amount of carbon that is fixed
per year minus the amount of fixed carbon that is oxidized during cellular respiration.
aboveground biomass - ANSWERtotal mass of living plant tissues in a given area
(excluding roots)
Tropical wet forests - ANSWERfound in equatorial regions of the globe where temps
and rainfall are high and annual variation is low
Subtropical Desert - ANSWERaway from equator, characterized by high average
annual temps, moderate variations in temp and very low precipitation.
Low productivity
Temperate Regions - ANSWERModerate temperatures relative to the tropics and
polar regions, and temperatures vary greatly with the season
Temperate Grasslands - ANSWERIncludes steppes and prairies that form in
temperate regions with relatively low precipitation
, Boreal Forest / Taiga - ANSWERforms on subarctic lands just south of the Arctic
Circle. Characterized by very cold winders and short, cool summers; temperature
variation is extreme.
Hadley Cell - ANSWERMajor cycle in global air circulation. Responsible for the
pattern of moisture lost and dry environments around 30N and 30S latitude.
Rain shadow - ANSWERwinds from the ocean cool and drop precipitation on one
side of a mountain range and not on the other side, creating high deserts
Global Warming - ANSWERcarbon dioxide pollution is causing this to occur
Littoral Zone - ANSWERconsists of shallow waters along the shore, where flowering
plants are rooted.
Limnetic Zone - ANSWERoffshore and comprises water what receives enough light
to support photosynthesis
Wetlands - ANSWERshallow-water habitats where the soil is saturated with water for
atleast part of the year
Genetic Diversity - ANSWERtotal genetic information contained within all individuals
of a species. It is measured as the number and relative frequency of all alleles
present in a species. Gene pool.
Species Diversity - ANSWERvariety of life-forms on Earth, measured as the number
and relative frequency of species in a particular region.
Taxonomic diversity - ANSWERevolutionary relationships among the species
present in a region. Some lineages are species-rich; others may be represented by
only a single living species.
Ecosystem diversity - ANSWERvariety of biotic communities in a region, along with
abiotic components such as soil, water, and nutrients.
Taxon-specific surveys - ANSWERspecies-rich groups at small and defined research
sites.
All-taxa surveys - ANSWERof the species that are present in a particular region.
Exotic Species - ANSWERnonnative competitors, diseases, or predators
Endangered species - ANSWERspecies that are almost certain to go extinct without
effective conservation programs, now are more likely to live on continents than on
islands
Habitat Loss - ANSWERSingle most important factor in the decline of endangered
species
