BIO 1442 Exam 3 Questions With Complete Solutions
abiotic components Correct Answer Nonliving chemical and
physical factors in the environment.
abundance Correct Answer how many organisms are found in
a given area
age structure Correct Answer the relative number of
individuals of each age in a population
aposematic coloration Correct Answer Bright warning colors
in animals with a chemical defense.
Aquaponics Correct Answer a system of aquaculture in which
the waste produced by farmed fish or other aquatic animals
supplies nutrients for plants grown hydroponically, which in
turn purify the water.
biogeochemical cycle Correct Answer process in which
elements, chemical compounds, and other forms of matter are
passed from one organism to another and from one part of the
biosphere to another
Biogeography Correct Answer geographical distribution of
species
biomanipulation Correct Answer can help restore polluted
communities
,Biomass Correct Answer the dry weight of all organic matter
contained in its organisms
Biome Correct Answer one of the world's major ecosystems,
classified
according to the predominant vegetation & characterized by
adaptations of organisms to that particular
environment
Biosphere Correct Answer the global ecosystem, the sum of
all the planet's ecosystems
biotic components Correct Answer organisms that are part of
environment
bottom-up model Correct Answer Unidirectional influence
from lower to higher trophic levels. (V --> H)
broadleaf biome Correct Answer - enough moisture for large
trees
- deciduous trees (lose leaves)
- seasonal variation in temperature
- leaf litter (slow nutrient cycling)
Bycatch Correct Answer The unintentional catch of nontarget
species while fishing
carbon cycle Correct Answer •Carbon-
based
organic molecules
are essential to all
, organisms
•Photosynthetic
organisms convert
CO2 to organic
molecules that are
consumed by
heterotrophs
•Carbon reservoirs
include fossil fuels,
soils and sediments,
solutes in oceans,
plant and animal
biomass, the
atmosphere, and
sedimentary rocks
carrying capacity (k) Correct Answer Largest number of
individuals of a population that a environment can support
Chapparal Biome Correct Answer -spiny shrubs
- mild, rainy winter; hot dry summer
- moderated by ocean currents
- periodic fires
- perennial shrubs, w/ annual plants
character displacement Correct Answer The tendency for
characteristics to be more divergent in sympatric populations of
two species than in allopatric populations of the same two
species.
