BIO 370 - Ecology Exam 1 questions
and correct answers rated A+
ecology - correct answer ✔✔ the scientific study of interactions between organisms and their
environment
ecology of individuals - correct answer ✔✔ how an organism's physiology and behavior
determines how it responds to the environment, and how it shapes the environment
population ecology - correct answer ✔✔ why do numbers of individuals of the same species
fluctuate in space and time
community ecology - correct answer ✔✔ how do interactions among different species and their
environment shape patterns on diversity and competition
ecosystem ecology - correct answer ✔✔ what controls the flow of energy and materials
between ecosystems and the environment
ecology of the biosphere - correct answer ✔✔ how does global climate and geography
influence environmental patterns and distributions of all living organisms
observational/surveys - correct answer ✔✔ observing patterns in natural ecosystems, but not
manipulating the environment, can determine potential connections in nature
experiment - correct answer ✔✔ manipulate/control an ecological factor - abiotic or biotic - and
observe the effects
, theoretical/mathematical modeling - correct answer ✔✔ use known relationships to predict
ecological outcomes
steps of the scientific method - correct answer ✔✔ 1. observe nature and ask a well-framed
question
2. use previous knowledge to predict potential answers to those questions (hypothesis)
3. test hypotheses with experiments, surveys, or theoretical models and analyze results using
statistics
weather - correct answer ✔✔ variation in temperature and precipitation over hours, days or
weeks
climate - correct answer ✔✔ a long-term. description of weather at a given location, based on
averages and variation measured over decades
climate controls organism distributions by influencing patterns in? - correct answer ✔✔ 1.
temperature (determines rates of biochemical reactions and metabolism)
2. precipitation (provides essential water for terrestrial organisms and maintains freshwater
ecosystems)
3. ocean currents (alter temperature and chemistry of marine ecosystems)
saturation - correct answer ✔✔ limit of the amount of water vapor that the air contains; if
vapor exceeds saturation point, precipitation occurs
Intertropical Convergence Zone - correct answer ✔✔ area where two atmospheric cells
converge and cause large amounts of precipitation
high pressure v. low pressure - correct answer ✔✔ cold air pushing down on earth's surface v.
warm air rising away from earth's surface
