Vocabulary
A measurement of the ability of a species to respond to the pressures of natural selection; the ability of individuals to survive to propagate their genes
What is fitness?
A species that is critical to the functioning of the ecosystem in which it lives because it affects the survival and abundance of many other species in its community
What is Keystone Species?
The range of different inherited traits within a species; high genetic diversity, wide variety of different traits within the species
A group of organisms that are closely related and can mate to produce fertile offspring; also the level of classification below genus and above subspecies
What is species?
How do human activities disrupt the hydrologic cycle and what are the consequences of that disruption?
What is damming rivers for hydroeloectrity, using water for farming, deforestation and the burning of fossil fuels.
The formation of new species as a result of evolution
What is speciation?
The process of becoming adapted to an environment; an anatomical, physiological, or behavioral change that improves a population's ability to survive
What is adaptation?
In biology, the ability of an organism to tolerate a chemical or disease-causing agent
What is resistance?
A species that has been identified to be in danger of extinction throughout all or a significant part of its range and that is thus under protection by regulations or conservation measures
What is endargeraged species?
How do human activities disrupt the carbon cycle and what are the consequences of that disruption?
What is Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
A segment of DNA that is located in a chromosome and that codes for a specific hereditary trait
What is gene?
A species that has been identified to be likely to become endangered in the foreseeable future
What is threated species?
The selective breeding of organisms (by humans) for specific desirable characteristics
What is artificial selection?
What are the three biogeochemical cycles discussed in environmental science?
What is the carbon cycle , nitrogen cycle and the water cycle?
How do human activities disrupt the nitrogen cycle and what are the consequences of that disruption?
What is fossil fuel combustion, which releases nitric oxides into the air that combine with other elements to form smog and acid rain.
The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do; a theory to explain the mechanism of evolution
What is natural selection?
The variety of organisms in a given area, the genetic variation within a population, the variety of species in a community, or the variety of communities in an ecosystem
What is biodiversity?
The theory that states that life on Earth gradually developed from simple to more-complex organisms
What is sciecntific Theory of evolution by natural selection?
What is the importance of decomposers to the overall biogeochemical cycle?
What is the flow of energy through an ecosystem.
Examples of adaption?
what is adapting to enviroment , an anamotical etc?
Genetic drift that results from a random event that drastically reduces the size of the population
What is bottleneck?
An index that combines the number and relative abundance of different species in a community
What is species diversity?
The variety of different habitats, communities and ecological processes
What is ecostyem diversity?
What is the gene located at?

During the process of artificial selectin it is done by humans or animals.
What is humans?
