DREXEL BIO 209 FINAL COMPLETE
PREPARATION GUIDE WITH BIOCHEMISTRY
AND CELLULAR PROCESSES REVIEW
◉ What do ecologists study?
Answer: Ecologists study the relationships between organisms and
their environments, including interactions within ecosystems.
◉ What are the ecological levels of organization?
Answer: The levels include individual, population, community,
ecosystem, biome, and biosphere.
◉ What are observational studies in ecology?
Answer: Observational studies involve watching and recording
behavior or phenomena without manipulation.
◉ What is an experiment in ecological research?
Answer: Experiments involve manipulating variables to determine
their effects on ecological outcomes.
◉ What is modeling in ecological studies?
,Answer: Modeling uses mathematical and computational techniques
to simulate ecological processes.
◉ How does earth-sun geometry affect global climate?
Answer: Earth-sun geometry influences the distribution of solar
energy, affecting climate patterns and biomes.
◉ What are terrestrial biomes?
Answer: Terrestrial biomes are large ecological areas defined by
climate, vegetation, and animal life.
◉ How do biomes differ in temperature and precipitation?
Answer: Biomes vary in average temperature and annual
precipitation, affecting the types of organisms that can thrive.
◉ What is eutrophication?
Answer: Eutrophication is the process where water bodies become
enriched with nutrients, leading to excessive plant growth.
◉ What are oligotrophic and eutrophic lakes?
Answer: Oligotrophic lakes are nutrient-poor and clear, while
eutrophic lakes are nutrient-rich and often murky.
, ◉ What are common gardens in ecological research?
Answer: Common gardens are experimental setups where different
species are grown under the same conditions to study their traits.
◉ What are the three processes of natural selection?
Answer: The three processes are variation, inheritance, and
differential survival and reproduction.
◉ What is a tolerance response curve?
Answer: A tolerance response curve shows how an organism's
performance varies with environmental conditions.
◉ What is acclimation?
Answer: Acclimation is the process by which organisms adjust to
changes in their environment, such as temperature.
◉ How do ectotherms thermoregulate?
Answer: Ectotherms regulate their body temperature through
external environmental conditions.
◉ What is relative humidity?
Answer: Relative humidity is the amount of moisture in the air
compared to the maximum amount the air can hold at that
temperature.
