BIO 201 Exam with Questions and
100% Correct Solutions
Succession (emergent property) - Answer the sequential appearance and
disappearance of species in a community over time.
species evenness - Answer relative abundance of each species
species richness - Answer the number of species in a community
species diversity - Answer The number and relative abundance of species in a biological
community.
trophic levels - Answer The hierarchical levels of the food chain through which energy
flows from primary producers to primary consumers, secondary consumers and so on.
, Photoautotrophs - Answer Organisms that use light as a source of energy to synthesize
organic substances.
Chemoautotrophs - Answer Organisms that use hydrogen sulfide or other chemicals
as energy source instead of light.
Biomagnification - Answer accumulation of pollutants at successive levels of the
food chain
semelparity - Answer Reproduction in which an organism produces all of its offspring
in a single event; also known as big-bang reproduction.
iteroparity - Answer Reproduction in which adults produce offspring over many
years; also known as repeated reproduction.
density dependent factors - Answer A limiting factor of a population wherein
large, dense populations are more strongly affected than small, less crowded ones.
density independent factors - Answer limiting factor that affects all populations in
similar ways, regardless of population size. ie natural disasters
primary succession - Answer An ecological succession that begins in an area where
no biotic community previously existed
secondary succession - Answer Succession following a disturbance that destroys
a community without destroying the soil
Epistemology - Answer study of knowledge
