FINAL EXAM BIO 1050- ANNE
BUNNELL QUESTIONS AND
ANSWERS
Effects of climate change on biological systems - Correct Answers -1. Trees and flowers
are blooming earlier at northern latitudes
2. Migratory birds are arriving at summer ranges earlier
3. Birds and butterflies are expanding geographic ranges northward
4. Arctic ice is thinning and melting
Why is global warming difficult to tackle? - Correct Answers -Because it is extremely
large in scope
Efforts to fight global climate change: - Correct Answers --Reduce fossil fuel
consumption
-Reduce deforestation/replant forests
-Increase energy efficiency of our homes and cars
-New innovative technologies
What happens to infectious disease when global climate change increase? - Correct
Answers -It may change/expand ranges.
What gases are released when we burn fossil fuels? - Correct Answers -Sulfur dioxide
and nitrogen dioxide
What do sulfur dioxide and nitrogen dioxide form when combined with was in the
atmosphere? - Correct Answers -Sulfuric acid and nitric acid
What is the first step in the greenhouse effect? - Correct Answers -Energy from the sun
passes easily through the atmosphere to warm the earths surface.
What is the second step in the greenhouse effect? - Correct Answers -Some energy is
reflected back toward space and escape the atmosphere.
What is the third step in the greenhouse effect? - Correct Answers -Some energy is
absorbed by greenhouse gases and remains trapped in the atmosphere, heating the air.
, What does deforestation cause? - Correct Answers -A loss of species and the release
of carbon.
First step in the carbon cycle - Correct Answers -Carbon present in the atmosphere is
absorbed by plants for photosynthesis.
Second step in the carbon cycle - Correct Answers -These plants are then consumed by
animals and carbon gets bioaccumulated into their bodies
Third step in the carbon cycle - Correct Answers -These animals and plants eventually
die, and upon decomposing, carbon is released back into the atmosphere.
Fourth step in the carbon cycle - Correct Answers -Some of the carbon that is not
released back into the atmosphere eventually becomes fossil fuels
Fifth step in the carbon cycle - Correct Answers -These fossil fuel are then used for
man-made activities, which pumps more carbon back into the atmosphere
Provisioning services - Correct Answers -Food, raw materials, fresh water, medicines
Regulating services - Correct Answers --Air, water, soil quality,
-carbon storage, climate regulation,
-pollination and biological control
Habitat services - Correct Answers -Habitats for species and maintenance of genetic
diversity
cultural services - Correct Answers --aesthetics and inspiration
-recreation and mental health
-tourism
Intrinsic value - Correct Answers -The inherent value of biodiversity, independent of its
value to humans
Extrinsic value - Correct Answers -The value of biodiversity to humans, often described
as ecosystem services, can be grouped together in four categories of services.
mass extinction - Correct Answers -A large extinction of species in a relatively short
period of time
background extinction - Correct Answers -gradual process of a species becoming
extinct
causes of extinction - Correct Answers -habitat loss and invasive species
