Environmental Science 101 Exam 1 Questions with
Correct Answers
Tragedy of the Commons (fishery) Correct Answer-shared resource or
service that is used, and overused, then it may become depleted or
destroyed
Exponential Growth Correct Answer-growing at an increasing rate
Feedback Loops Correct Answer-loops that close the cause and effect
relationship between a condition and its growing or
slowing action
Ecosystem Services Correct Answer-ecosystems of our planet provide
us with
everything we require for life. We call these things ecosystem services.
Provisioning services Correct Answer-(things we consume or utilize)
Medicine from plants, water, timber to build houses
Regulating services Correct Answer-include pollination, erosion control,
water purification, air
quality, carbon sequestration and climate control.
Cultural services Correct Answer-(things that inspire, teach or entertain)
, Hiking, cultural importance of Salmon to native people, knowing that
there are wild places
"untouched" by humans still out there (my own personal inspiration).
supporting services Correct Answer-include seed dispersal, nutrient
cycling, and primary production.
Carbon Cycle Correct Answer-
word or chemical equation for photosynthesis and respiration Correct
Answer-6CO2 + 6H2O + Energy from Sun--> C6 H12 06 +6 O2
co2 from atmosphere + water from plants + energy from sun ----->
carbohydrates for plants + 6 o2 to the atmosphere
Greenhouse effect Correct Answer-sun emitting radiation, some gets
reflected back to space by clouds or ice, some gets absorbed by land
surfaces and then radiated back out of land to the atmosphere as infrared
radiation (heat). The heat hits molecules and they wiggle and heat things
up, and the land reabsorbs infrared. this cycle repeats.
Explain how Carbon dioxide levels in the atmosphere are linked to
periods of glaciation and interglacial periods back over 100,000 year
cycles
