Ecology Final Exam Actual Questions and
Answers 2024/2025 with complete
solution
Define Ecology - ✔ANASWER✔-The study of interactions between
organisms and their environment
Ecology - ✔ANASWER✔-scientific study of interactions among
organisms and between organisms and their environment
Species - ✔ANASWER✔-A population or group of populations
whose members have the potential to interbreed in nature and
produce viable, fertile offspring
,Keystone species - ✔ANASWER✔-a species that influences the
survival of many other species in an ecosystem
dominant species - ✔ANASWER✔-those species in a community
that are the most abundant or that collectively have the highest
biomass
Disturbance - ✔ANASWER✔-A discrete event that disrupts an
ecosystem or community. Examples of natural disturbances
include fires, hurricanes, tornadoes, droughts, and floods.
Examples of human-caused disturbances include deforestation,
overgrazing, and plowing.
primary succession - ✔ANASWER✔-an ecological succession that
begins in an area where no biotic community previously existed
secondary succession - ✔ANASWER✔-succession on a site where
an existing community has been disrupted
extirpation - ✔ANASWER✔-the extinction of a species from
specific geographic areas
extinction - ✔ANASWER✔-disappearance of a species from all
parts of its geographical range
,primary productivity - ✔ANASWER✔-synthesis of organic
materials by green plants using the energy captured in
photosynthesis
secondary productivity - ✔ANASWER✔-The rate at which
consumer convert chemical energy from their food into their own
biomass
GPP - ✔ANASWER✔-Gross primary productivity
NPP - ✔ANASWER✔-The Gross Primary Productivity minus the
respiration rate of autotrophs is equal to
biodiveristy - ✔ANASWER✔-the vairety of organisms considered
at all levels from populations to ecosystems.
biological oxygen demand - ✔ANASWER✔-the amount of oxygen
needed by microorganisms to decompose biological wastes into
carbon dioxide, water, and minerals.
, acid precipitation - ✔ANASWER✔-rain containing acids that form
in the atmosphere when industrial gas emissions (especially sulfur
dioxide and nitrogen oxides) combine with water
energy budgets - ✔ANASWER✔-all gains of incoming energy and
all losses of outgoing energy in a system (Earth)
SLOSS - ✔ANASWER✔-Single Large or Several Small. A reserve
should be large enough to support viable populations of
endangered species, keep ecosystems intact, and isolate critical
core areas from external forces
pheromones - ✔ANASWER✔-odorless chemicals that serve as
social signals to members of one's species
cultural eutrophication - ✔ANASWER✔-An increase in biological
productivity and ecosystem succession caused by human
activities.
green house effect - ✔ANASWER✔-process by which heat is
trapped by gasses in earth's atmophere
GMO - ✔ANASWER✔-genetically modified organism
