BIOL 211 IOWA STATE FINAL EXAM
QUESTIONS & ACCURATE CORRECT
ANSWERS ALREADY PASSED
Ecology - correct answer ✔✔study of interactions between organisms and their environment.
Physiological Ecology - correct answer ✔✔Investigates how organisms are physiologically
adapted to environment
Behavioral Ecology - correct answer ✔✔How behavior of individual contributes overall
Population - correct answer ✔✔A group of individuals of the same species that live in the same
area at the same time
Community - correct answer ✔✔A group of potentially interacting species living in the same
place. Bound together by the network of influence the species have on one another.
Ecosystem - correct answer ✔✔The flow of energy and cycling of chemical elements among
organisms within a community and between organisms in an environment. Focuses on abiotic
factors.
Landsapes - correct answer ✔✔relationships between spatial patterns and ecological processes
Temperature - correct answer ✔✔affects biological processes; most important factor of
distribution of organisms. To do with the inability of most organisms to regulate their own body
temperature.
, Wind - correct answer ✔✔Can amplify effects of temperature. Increases heat loss in organisms.
Intensifies oceanic wave action.
Light Availability - correct answer ✔✔Different plants need different amounts. Effects related to
deep water and photosynthesis.
Abiotic Factors affecting species distribution and abundance - correct answer ✔✔Examples:
water availability, light availability, salt, pH, solar radiation and temperature, air circulation,
elevation, climate
The Biosphere - correct answer ✔✔The thin layer of Earth where all life exists (all ecosystems
combined). Extends several kilometers into the Earth AND up into the atmosphere.
Population Ecology - correct answer ✔✔Study of how and why the number of individuals in a
population changes over time and space. Focuses on processes.
Metapopulation - correct answer ✔✔A population of populations (of the same species)
connected by migration. Ex. mass salmon migrations upstream rivers to breed.
Population Attributes - correct answer ✔✔Distribution, size, density, dispersion, sex ratios, life
history traits, change through time, genetic characteristics, composition of gene pool.
Random distributions - correct answer ✔✔Indicate no strong interactions among members of a
population. Uncommon.
Clumped distributions - correct answer ✔✔may result from habitat requirements. Positive
interactions among individuals. Very common
Uniform distributions - correct answer ✔✔Indicate negative interactions among individuals.
