Questions with Correct Answers 2025
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
