1. Biogeochemical Cycles - ANSWER ✔ The movement of abiotic factors
between the living and nonliving components within ecosystems; also
known as nutrient cycles (i.e., water cycle, carbon cycle, oxygen cycle, and
nitrogen cycle).
2. The Water Cycle - ANSWER ✔ Evaporation, condensation, precipitation,
run off, transpiration, infiltration. Humans impact this by storing water in
reservoirs, irrigation, deforestation, and putting chemicals in it
3. Condensation - ANSWER ✔ The change of state from a gas to a liquid
4. Run off - ANSWER ✔ The draining away of water (or substances carried in
it) from the surface of an area of land, a building or structure, etc.
5. Transpiration - ANSWER ✔ Evaporation of water from the leaves of a plant
6. Infiltration - ANSWER ✔ Flow of water from the land surface into the
subsurface
,7. The Carbon Cycle - ANSWER ✔ The organic circulation of carbon from the
atmosphere into organisms and back again. Humans impact this by burning
fossil fuels and cutting down trees,
8. The Nitrogen Cycle - ANSWER ✔ The transfer of nitrogen from the
atmosphere to the soil, to living organisms, and back to the atmosphere.
Humans impact this by altering the amount of nitrogen that is stored in the
biosphere.
9. The Phosphorus Cycle - ANSWER ✔ The movement of phosphorus atoms
from rocks through the biosphere and hydrosphere and back to rocks.
10.The Sulfur Cycle - ANSWER ✔ Cyclic movement of sulfur in various
chemical forms from the environment to organisms and then back to the
environment. Humans impact this by burning coal, natural gas, and other
fossil fuels which greatly increases the amount of sulfur in the atmosphere
and ocean and depleted the sedimentary rock sink
11.Mutualism - ANSWER ✔ A relationship between two species in which both
species benefit
12.Commensalism - ANSWER ✔ A relationship between two organisms in
which one organism benefits and the other is unaffected
13.Intraspecific competition - ANSWER ✔ Competition among members of the
same species
14.Interspecific Competition - ANSWER ✔ Competition between members of
different species
,15.Resource Partitioning - ANSWER ✔ When species competing for similar
scarce resources evolve specialized traits that allow them to share resources
by using parts of them, using them at different times, or using them in
different ways
16.How does the phosphorus cycle differentiate from other biogeochemical
cycles? - ANSWER ✔ It does not include a gas phase
17.the five indirect drivers of change - ANSWER ✔ Demographic, Economic,
Sociopolitical, Science and Tech, Cultural and Religious
18.seven direct drivers of change - ANSWER ✔ Changes in local land use and
cover
Species introduction and removal
Technology adaptation and use
External inputs
Harvest and resource consumption
Climate change
Natural physical and biological drivers
19.Birth Rate - ANSWER ✔ individuals born per 1,000 individuals/year
20.Death Rate - ANSWER ✔ individuals who die per 1,000 individuals/year
21.Growth rate - ANSWER ✔ (birthrate + immigration) - (death rate +
emigration) expressed as a percentage of the total pop.
, 22.DDT - ANSWER ✔ A synthetic organic compound used as an insecticide.
Like other chlorinated aromatic hydrocarbons, it tends to persist in the
environment and become concentrated in animals at the head of the food
chain. Its use is now banned in the U.S., but is still used in other countries.
23.Labor-Intensive Subsistence Agriculture - ANSWER ✔ Type of agriculture
that requires large levels of human and animal labor to be successful
24.Subsistence Agriculture - ANSWER ✔ Agricultural practice used mostly in
developing countries. Production of food primarily for consumption by the
farmer's family
25.Industrial Agriculture - ANSWER ✔ A form of agriculture that uses large
scale mechanization and fossil fuel combustion, enabling farmers to replace
horses and oxen with faster and more powerful methods of farming.
26.Monocropping (Monoculture) - ANSWER ✔ The cultivation of a single
crop on a farm or in a region or country; a single, homogeneous culture
without diversity or dissension.
27.Intercropping (Polyculture) - ANSWER ✔ Planting different types of crops
in alternating bands or other spatially mixed arrangements.
28.Crop Rotation (Polyculture) - ANSWER ✔ The planting of different crops
in a field each year to maintain the soil's fertility.
29.Integrated Pest Management - ANSWER ✔ A combination of methods used
to effectively control pest species while minimizing the disruption to the
environment. These methods include biological, physical, and limited
