BIOL 1108 Exam 1 | UPDATED Questions with 100% Verified
Answers
Q1: species
A: can mate and produce healthy individuals that
can reproduce
Q2: species
A: can mate and produce healthy individuals that
can reproduce
Q3: population
A: all of the individuals of a single species that can
interact
Q4: community
A: all of the populations of living things that
interact in a place
Q5: ecosystem
A: a biological community of interacting organisms
and their physical environment (biotic and
abiotic)
Q6: biosphere
A: sum of all ecosystems
Q7: abiotic (environmental) aspects of an ecosystem
A: climate (averages and seasonality)
geology (bedrock, water, soils, topography)
disturbance (natural/human, scale, frequency,
and intensity)
Q8: biotic (organisms) aspects of an ecosystem
A: biodiversity
biomass
species interactions
invasive/keystone species
,Q9: scale
A: no defined size of an ecosystem
no boundaries (mostly)
Q10: how does elevation impact abiotic characterisitics?
A: temp decreases
precip increases
O2 decreases
soil quality decreases
pressure decreases
Q11: mountains and biodiversity?
A: biodiversity decreases when going up a
mountain because most organisms cannot
handle the extreme cold
Q12: elevation vs latitude on a mountain
A: Going up a mountain can produce climate and
biome changes similar to moving toward a
higher latitude, but elevation produces those
changes over a much shorter distance
elevation changes faster!
Q13: MSH before eruption
A: Old growth forest that had never been logged;
diverse forests and lots of wildlife
rich soil with lots of available nutrients for plant
growth
temperate rainforest biome
Q14: MSH post eruption
A: 230 sq miles of forest blown down up to 17
miles away from MSH
everything in the pumice plain was covered up
to 6 ft in tephra/ash
NOTHING in pumic plain survived (covered by
pyroclastic flow)
Q15: MSH south slope
A: same as pre eruption ecosystem! often used as a
"control"
, Q16: pumice plain
A: most impact, moonscape, nothing alive
Q17: blowdown zone
A: trees snapped off at ground, large area
Q18: scorch zone
A: least impacted, furthest away, some living plants
Q19: MSH tephra
A: volcanic ash
became the new soil
very hard for vegetation to grow
