BIO 182 FINAL EXAM QUESTIONS AND
ANSWERS WITH SOLUTIONS 2024
ecology; what is it's purpose? - ANSWER -study of how organisms interact with their environment
-to understand the distribution and abundance of organisms
population - ANSWER group of individuals of the same species living in the same area, at the same time
community - ANSWER consists of species that interact with one another within a particular area
ecosystem - ANSWER consists of all organisms in a particular region, along with non-living components
abiotic components - ANSWER air, water, and non-living parts of soil
range - ANSWER geographical distribution; abiotic & biotic determine range
biomes - ANSWER major groupings of plant and animal communities defined by a dominant vegetation
type
climate - ANSWER the prevailing, long-term weather conditions found in an area
tropical wet forests (rain forests) - ANSWER found in equator regions where temperatures are high and
annual temperature is very low; produce abundant plant growth, lead to high above-ground biomass
boreal forest (taiga) - ANSWER forms on subarctic lands, dominated by highly cold-tolerant conifers;
productivity is low, above-ground biomass is high because slow-growing tree species may be long-lived
and become big
tundra - ANSWER found throughout the arctic regions; low productivity and low above-ground biomass
and its treeless
, permafrost - ANSWER soils are in a permanently frozen state; limits both the release and uptake of
nutrients
simulation studies - ANSWER are based on computer models of weather patterns in local regions
observational studies - ANSWER based on long-term monitoring at fixed site
historical studies - ANSWER examine the relationship b/w CO2 levels, climate change, & the distribution
and abundance of organisms based on events millions of years ago
experiments - ANSWER designed to simulate changed climate conditions and to record responses by the
organisms present
behavior - ANSWER an action or response to a stimulus
behavioral biology - ANSWER study of how organisms respond to particular stimuli from those
environments
proximate causation (mechanistic) - ANSWER explains how actions occur
ultimate causation (evolutionary) - ANSWER explains why actions occur
fixed action patterns (FAP's) - ANSWER highly inflexible stereotypical behavior patterns
innate behaviors - ANSWER behavior that is inherited and shows little variation based on learning or the
individuals condition
cost benefit analysis - ANSWER animals appear to weigh the costs and benefits of responding to a
particular situation in various ways
foraging - ANSWER when animals seek food
