Case Studies
These two gasses are naturally occurring greenhouse gasses.
What are methane and carbon dioxide?
This type of system experiences exchanges of energy or matter with another
What is an open system?
What is a drastic population crash?
These are the three types of biodiversity
What are genetic, species, and habitat?
The phenomenon seen in plants, is an aspect of the hydrologic cycle, and aids in keeping plants 'cool'
What is transpiration?
This feature of ice cores help scientists determine the relative concentration of gasses during a given time period
What are gas bubbles?
These two interconnected components of environmental systems interact with one another, influencing their respective systems.
What are nonliving & living factors?
What is (Births + Immigration) - (Deaths + Emigration)
This type of biodiversity is the catalyst for species diversity
What is genetic biodiversity?
What is infiltration?
This phenomenon, caused by high air pollution, was deemed the cause of dying red spruce populations
What is acid rain?
The difference in inputs and outputs in regards to a given system
What is flux?
This characteristic of a given population results in a higher adaptability and fitness within a given environment
What is genetic diversity?
Cyclical periods of large losses in overall biodiversity are accredited to this natural event
What are mass extinctions?
The phenomenon increasing the net amount of carbon fixed in oceans, resulting from increasing atmospheric carbon dioxide
What is ocean acidity?
The restoration plan for the Florida Everglades watershed was adopted by Congress as part of which act?
What is the Water Resource Development Act of 2000?
This equation is used to calculate the mean residence time of a steady system
What is MRT=(pool)/(flux in or out)?
A general assessment for the health of an ecosystem, the decline in beaver populations would be an example of this
Rich biodiversity can aid in the natural prevention of this species, through high adaptability and natural predators
Wat are exotic/invasive species?
These two natural processes 'fix' nitrogen into a state readily available for plant use.
What are lightning and cyanobacteria?
This number represents the approximate amount of water drawn from Mono Lake daily for use in Los Angeles in 1941
The overconsumption of water from Mono Lake during the 20th century resulted in it being classified as this type of system
What is density-dependent growth?
The four types of genotypic diversity which are derived from variations in genes.
What are variation among individuals, individuals within a population, populations, and species
A majority of ecosystems have a carrying capacity dependent on the concentration of this macronutrient
What is nitrogen?
