answers
ecology; what is it's purpose? - correct answer ✔✔-study of how organisms interact with their
environment
-to understand the distribution and abundance of organisms
population - correct answer ✔✔group of individuals of the same species living in the same area, at the
same time
community - correct answer ✔✔consists of species that interact with one another within a particular
area
ecosystem - correct answer ✔✔consists of all organisms in a particular region, along with non-living
components
abiotic components - correct answer ✔✔air, water, and non-living parts of soil
range - correct answer ✔✔geographical distribution; abiotic & biotic determine range
biomes - correct answer ✔✔major groupings of plant and animal communities defined by a dominant
vegetation type
climate - correct answer ✔✔the prevailing, long-term weather conditions found in an area
tropical wet forests (rain forests) - correct 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) - correct 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 - correct answer ✔✔found throughout the arctic regions; low productivity and low above-ground
biomass and its treeless
permafrost - correct answer ✔✔soils are in a permanently frozen state; limits both the release and
uptake of nutrients
simulation studies - correct answer ✔✔are based on computer models of weather patterns in local
regions
observational studies - correct answer ✔✔based on long-term monitoring at fixed site
historical studies - correct answer ✔✔examine the relationship b/w CO2 levels, climate change, & the
distribution and abundance of organisms based on events millions of years ago
experiments - correct answer ✔✔designed to simulate changed climate conditions and to record
responses by the organisms present
behavior - correct answer ✔✔an action or response to a stimulus
behavioral biology - correct answer ✔✔study of how organisms respond to particular stimuli from those
environments
proximate causation (mechanistic) - correct answer ✔✔explains how actions occur
ultimate causation (evolutionary) - correct answer ✔✔explains why actions occur
fixed action patterns (FAP's) - correct answer ✔✔highly inflexible stereotypical behavior patterns
