study of examines how organisms interact with their environment -
CORRECT ANSWER -ecology
ecologists look to identify and explain - CORRECT ANSWER -patterns
environment is associated with features/traits of an ecosystem - CORRECT ANSWER -
abiotic
"organisms" is associated with features/traits of an ecosystem - CORRECT ANSWER -
biotic
what things are included in the environmental/abiotic features of an ecosystem? -
CORRECT ANSWER -climate, geology, disturbances (human scale, natural, recurrence)
what things are included in the organisms/biotic features of an ecosystem? -
CORRECT ANSWER -
biodiversity, species interactions, distribution and quantity of individual species or groups of
species, invasive or keystone species
which two factors of an ecosystem are the most important? - CORRECT ANSWER -
temperature and precipitation
list the order of how something goes from individual to landscape - CORRECT ANSWER -
individual
population
,metapopulation
guild
community
ecosystem
stand
landscape
at the most fundamental level plant location is determined by .... - CORRECT ANSWER -
photosynthesis
what is the relationship between temperature and photosynthesis? - CORRECT ANSWER -
photosynthetic rate increases (to a point) w temperature
photosynthesis is facilitated with - CORRECT ANSWER -enzymes
t/f: there is no defined size of an ecosystem and ecosystems have no boundaries -
CORRECT ANSWER -true
how populations change in response to changes in environment - CORRECT ANSWER -
population ecology
how the relative abundance of species or biodiversity changes with the environmental -
CORRECT ANSWER -community ecology
how rapid climate change impacts all levels of biological organization - CORRECT ANSWER -
climate change ecology
, population ecologists study the characteristics of as they relate to their environ
ment - CORRECT ANSWER -populations
demographics means - CORRECT ANSWER -
study of births and deaths within a population; age structures of populations
demographic chart of tree species in forest stand: mostly old, not really any young tress ali
ve - CORRECT ANSWER -senescence- decreasing importance
demographic chart of tree species in forest stand: no old trees, only tree population alive i
s young - CORRECT ANSWER -increasing importance/dominance
demographic chart of tree species in forest stand: most individuals are young, but it distrib
utes up semi-
evenly. there are mostly young but a good amount of adult age trees, and few VERY old o
nes - CORRECT ANSWER -sustained importance
what two types of population growth models are there? - CORRECT ANSWER -
exponential growth and logistic growth
describe exponential growth graph - CORRECT ANSWER -
no limitations on resources, per capita GROWTH RATE (r) stays constant, population g.r. incr
eases; exponential graoh
describe logistic growth graph - CORRECT ANSWER -
limited resources limit the population growth over time; looks like it would be an exponent
ial graph but then levels out due to limiting resources
what is the equation for how many individuals there are in a model? - CORRECT ANSWER -
Nt1= nt0 + b- D
