autotroph - Answer✅✅organism that can capture energy from sunlight or
chemicals and use it to produce its own food from inorganic compounds; also called
a producer
biosphere - Answer✅✅part of Earth in which life exists including land, water, and
air or atmosphere
community - Answer✅✅assemblage of different populations that live together in a
defined area
consumer - Answer✅✅organism that relies on other organisms for its energy and
food supply; also called a heterotroph
ecology - Answer✅✅scientific study of interactions among organisms and between
organisms and their environment
ecosystem - Answer✅✅collection of all the organisms that live in a particular place,
together with their nonliving environment
,food chain - Answer✅✅series of steps in an ecosystem in which organisms transfer
energy by eating and being eaten
food web - Answer✅✅network of complex interactions formed by the feeding
relationships among the various organisms in an ecosystem
heterotroph - Answer✅✅organism that obtains energy from the foods it consumes;
also called a consumer
population - Answer✅✅group of individuals of the same species that live in the
same area
producer - Answer✅✅organism that can capture energy from sunlight or chemicals
and use it to produce food from inorganic compounds; also called an autotroph
species - Answer✅✅group of similar organisms that can breed and produce fertile
offspring
trophic level - Answer✅✅step in a food chain or food web
abiotic factors - Answer✅✅physical, or nonliving, factor that shapes an ecosystem
biotic factors - Answer✅✅biological influence on organisms within an ecosystem
commensalisms - Answer✅✅symbiotic relationship in which one member of the
association benefits and the other is neither helped nor harmed
mutalism - Answer✅✅symbiotic relationship in which both species benefit from
the relationship
niche - Answer✅✅full range of physical and biological conditions in which an
organism lives and the way in which the organism uses those conditions
predation - Answer✅✅interaction in which one organism captures and feeds on
another organism
parasitism - Answer✅✅symbiotic relationship in which one organism lives in or on
another organism (the host) and consequently harms it
pioneer species - Answer✅✅first species to populate an area during primary
succession
primary succession - Answer✅✅succession that occurs on surfaces where no soil
exists
symbiosis - Answer✅✅relationship in which two species live closely together
, carrying capacity - Answer✅✅largest number of individuals of a population that a
given environment can support
emigration - Answer✅✅movement of individuals out of an area
exponential growth - Answer✅✅growth pattern in which the individuals in a
population reproduce at a constant rate
immigration - Answer✅✅movement of individuals into an area occupied by an
existing population
logistic growth - Answer✅✅growth pattern in which a population's growth rate
slows or stops following a period of exponential growth
population density - Answer✅✅number of individuals per unit of area
gene pool - Answer✅✅combined genetic information of all the members of a
particular population
genetic drift - Answer✅✅random change in allele frequencies that occurs in small
populations
genetic equilibrium - Answer✅✅situation in which allele frequencies remain
constant
speciation - Answer✅✅formation of new species
acid rain - Answer✅✅rain containing nitric and sulfuric acids
biodiversity - Answer✅✅biological diversity; the sum total of the variety of
organisms in the biosphere
biological magnification - Answer✅✅increasing concentration of a harmful
substance in organisms at higher trophic levels in a food chain or food web
invasive species - Answer✅✅plants and animals that have migrated to places
where they are not native
nonrenewable resource - Answer✅✅resource that cannot be replenished by
natural processes
renewable resource - Answer✅✅resource that can regenerate quickly and that is
replaceable
ATP - Answer✅✅one of the principal chemical compounds that living things use to
store and release energy
