BIO 121 Exam 1 Chapters 1-4 Questions With Complete
Solutions
Adaptations Correct Answers traits that lead to better
reproductive success over time
age structure Correct Answers the relative number of
individuals of different ages within a population
Aldo Leopold Correct Answers wrote "The Land Ethic" argue
people should view themselves and the land as members of the
same community, therefor we must treat the land in an ethical
manner
Allopatric Speciation Correct Answers single population gets
separated geographically, long term isolation can cause
adaptations in one group, once the pops come back together,
they can no longer reproduce
Anthropocene Correct Answers 6th mass extinction:
- destruction of natural habitat
- pollution of air,water,soil
-non native species introduced
-alteration of climate
Anthropocentrism Correct Answers human centered view
Asian Carp are threatening what? Correct Answers Carp were
imported to clean up infestations of algae and snails, they are
spreading to great lakes due to not having any predators
,Atmosphere Correct Answers surrounding air
background extinction Correct Answers graudal occurence
Biocentrism Correct Answers ascribes inherent value to certain
living things
Biomes Correct Answers major regional complexes of similar
communities - recognized primarily by the dominant plant tye
and vegetaion structure
Biosphere Correct Answers encompasses Earth's biotic and the
abiotic portions they interact with
Both participants are benefited Correct Answers MUTUALISM
Carbon Cycle Correct Answers -producers pull CO2 to produce
sugars
-consumption of organic molecules by consumers/decomposers
releases CO2
CARBON CYCLE: Why do we care about this cycle? What
environmental issues are important for this cycle? Why is this
cycle important to humans?What spheres are involved in the
cycle?How do humans modify the cycle? Correct Answers
carbon is the backbone of biological molecules, extremely
important for climate change.
lithosphere, hydrosphere, biosphere, and atmosphere.
global warming
, Carrying capacity Correct Answers maximum population size
of a species that a given environment can sustain
cellular respiration Correct Answers releases chemical energy
Climate Diagrams/Climatographs Correct Answers depict
seasonal changes in temperature and precipitation and help to
tell the story of a biome
Coevoltion Correct Answers adapt and counter-adapt to each
other
Communtiy Correct Answers an assemblage of populations of
organisms living in the same area at the same time
Competition Correct Answers multiple organisms seeking the
same limited resource
declines in biodiversity come from Correct Answers Extinction
or Emigration
Density Dependent Factors Correct Answers limiting factors
where population density can enhance or diminish the impact
Ex: Predation, disease
Density Independent Factors Correct Answers limiting factors
that don't depend on density
Ex: temperature extremes, natural disasters
