BIO 320 EXAM 1 NEWEST 2025 ACTUAL EXAM
COMPLETE 100 QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+
Frank Preston - ans -Developed a way to visualize patterns of variation in
abundance of different species.
, Calculate species diversity with? - ans -Simpson's index and Shannon's index
Simpsons and Shannons index both incorporate? - ans -Species richness and
evenness but in different ways
What abiotic factors influence the amount of life an area can sustain? - ans -Light,
water, and oxygen
Landscape Ecology - ans -Consider the spatial arrangement of habitats at different
scales and examines how they influence individuals, populations, communities,
and ecosystems.
Legacy Effects - ans -Historical processes that have long-lasting influences on
current ecology of an area
Ecosystem Engineers - ans -Animals that can alter the habitats in a landscape
Human habitations can cause? - ans -Habitat heterogeneity
True or false; humans are the most extensive ecosystem engineers? - ans -True
Local/Alpha Diversity - ans -The number of species in a relatively small area of
homogenous habitat
Regional/Gamma Diversity - ans -The number of species in a relatively large area
geographic area
Number of species at a local scale is? - ans -Less than the number of species at the
regional scale because species prefer different habitats
Beta Diversity - ans -The number of species that differ in occurrences between 2
habitats
Regional Species Pool - ans -Collection of species that occur within a region
Biodiversity is built from what 3 features? - ans -Ecosystem diversity, species
diversity, genetic diversity
