APES Final Exam 2023-2024ACTUAL
QUESTIONS AND CORRECTANSWERS
What is a keystone species? - CORRECT ANSWERS a species on which
other species in an ecosystem largely depend, such that if it were removed the
ecosystem would change drastically.
Abiotic Factors - CORRECT ANSWERS are the non-living parts of an
organism's habitat.
What is the largest reservoir of the nitrogen cycle? - CORRECT ANSWERS
atmosphere
How is nitrogen added to the atmosphere? - CORRECT ANSWERS
denitrification by denitrifying bacteria
Stage 1 of DTM - CORRECT ANSWERS Low Growth: A pre-industrial
agrarian society with a High CBR, High CDR, no population growth
Stage 2 of DTM - CORRECT ANSWERS High Growth: Industrializing
society with a CBR that remains high but stable, a CDR that declines
dramatically, and a rapid increase in population
Stage 3 of DTM - CORRECT ANSWERS Moderate Growth, Rapidly
Declining CBR, Moderately Declining CDR
Stage 4 of DTM - CORRECT ANSWERS Low Growth: A Modern
Industrialized Country with a low CBR, low CDR
, Stage 5 of DTM - CORRECT ANSWERS Negative Growth - More
Deaths than Births
Aquatic Biomes - CORRECT ANSWERS Water covers nearly 75
percent of the earth's surface, in the form of oceans, lakes, rivers, etc. These
areas can primarily be divided up into freshwater or saltwater bioimes. Are vital
sources of drinking water.
How is carbon added to the atmosphere? - CORRECT ANSWERS
cellular respiration, volcanic action, burning fossil fuels, decomposition
of organic materials
Percent Change Formula - CORRECT ANSWERS Percent Change
=(final value−initial value)/initial value×100
R-Selected Species - CORRECT ANSWERS Species that reproduce
early in their life span and produce large numbers of usually small and short-
lived offspring in a short period. Ex: Invasive Species, insects
K-slected species - CORRECT ANSWERS few offspring, slower growth
as they near carrying capacity and exercise as they near carrying capacity and
exercise more parental care
ie: elephant produces one offspring every 4 or 5 years, but nurturing by a herd
increase the likelihood of it surviving to maturity
Tropical Rainforest Biomes - CORRECT ANSWERS have more species
than all other biomes
warm all year long, large amounts of rain, high species richness, low nutrient
levels in soil
