How many pounds are there in 45 kilograms? correct answers 99.208 lbs
(2.2 lbs per kg)
In MPH, how fast is 50 km per hour? correct answers 31.0686
(1.61 km per m)
How many milliliters of liquid are in a 32 ounce drink (including the ice)? correct answers
946.353 mL
(29.57 mL per ounce)
You know that a barrel of oil contains 42 gallons, and 1 gallon contains 128 ounces, so how
many milliliters are there in a barrel o oil? 1 ounce = 29.57 mL correct answers 158,968.32 mL
(42*128*29.57)
Why was the book called "Silent Spring?" correct answers Rachel Carson, the author, wrote
about a future with no songbirds due to pesticide pollution
What is a species? Are there exceptions? correct answers the different kinds of living things in a
community; this definition does not work for organisms that do not mate to produce offspring
What is an ecotone and why are ecotones important? correct answers a transitional region
between ecosystems; they are important because they have perfect characteristics for certain
species that are vital for the surrounding ecosystems
What is the difference between a compound, a molecule, and an atom? correct answers atoms are
the building blocks of matter; molecules are two or more atoms of the same or different kinds of
atoms bonded together; a compound is two or more different kinds of atoms bonded together
Describe the process of photosynthesis. correct answers the process that happens in plants that
converts water, carbon dioxide, and sunlight into glucose for energy; oxygen is a bi-product and
is released back into the atmosphere
Describe the process of cellular respiration. correct answers the process by which organic
molecules are broken down inside each cell, producing energy for use by that cell; opposite of
photosynthesis
What is the difference between population growth and population growth rate? correct answers
population growth is the total change in population, whereas population growth rate is the total
number of people added to the population divided by the midyear population
, What is the different between birth rate and total fertility rate? correct answers birth rate is the
number of live births per thousand of population each year; total fertility rate is the average
number of kids each woman has over her lifetime
What is the difference between top-down regulation and bottom-up regulation? What is an
example of each? correct answers top-down is the control of a population (species) by predation
(fox eating rabbit), whereas bottom-up is the control of a population as a result of scarcity of a
resource such as food (no more rabbits for fox to eat)
What is the difference between mutualism and commensalism? What is an example of each?
correct answers mutualism is a relationship between two species where both species benefit
(pollinators receive nutrition and plants receive pollination), whereas commensalism is a
relationship between two species where one benefits and the other is unaffected (buffalo stir up
insects insects that cattle egrets eat)
What is the difference between keystone species and endemic species, and why/how are each
one important? correct answers a keystone species is a species that is crucial to the survival of an
ecosystem, whereas an endemic species is one that is unique to a certain region; each are
important because they are crucial to the efficiency of their respective ecosystems
What is the difference between R-strategists and K-strategists? correct answers R-strategists
produce lots of offspring, but leave their survival to nature; K-strategists don't produce as many
offspring, but they care and protect their young
Why is resource partitioning important? correct answers without it, some species would run out
of resources due to intense competition
What was the Industrial Revolution and why are we discussing it in an environmental sciences
class? correct answers the IR is the era that technology began to be powered by fossil fuels, such
as coal, oil, or natural gas, instead of animal/human power; an environmental science class
discusses this because it is the beginning of the world's pollution problem
What is the difference between primary succession and secondary succession? correct answers
primary succession is the process of initial invasion and progression from one biotic community
to another (starts with no soil); secondary succession is the process of life re-entering an area that
was once cleared by some disturbance such as fire, flood, or humans (starts with pre-existing
soil)
What is the difference between conservation and preservation? correct answers the goal of
preservation is to ensure species and ecosystem continuity regardless of their potential utility; the
goal of conservation is to ensure species and ecosystem continuity because of their potential
utility
What does Coca-Cola have to do with coral reefs? correct answers the atmospheric CO2 in
carbonic acid that is used to carbonate the Coke often ends up in oceans, when this happens
ocean acidifcation from excess CO2 kills zooxanthellae and coral, destroying coral reefs.
