Abiotic
non-living chemical and physical factors in the environment
Biotic
produced by life or living organisms
Ecosystem
a system formed by the interaction of a community of organisms with their physical environment
Nutrient Cycle
The passage of a nutrient or element through an ecosystem, including its assimilation and release by various organisms and its transformation into various organic or inorganic chemical forms.
Producers
(autotrophs) utilize energy from the sun and nutrients from the abiotic environment to perform photosynthesis and grow.
Consumers
relies upon the feeding of other organisms for survival
Energy Flow
flow of energy through a food chain.
Supporting Services
Ecosystem services that are necessary for the production of all other ecosystem services
Provisioning Services
The products obtained from ecosystems, including, for example, genetic resources, food and fiber, and fresh water.
Regulating Services
The benefits obtained from the regulation of ecosystem processes, including the regulation of climate, water, and some human diseases
Cultural Services
non-material benefits people obtain from ecosystems through spiritual enrichment, cognitive development, reflection, recreation
Hypothesis
supposition or tentative explanation for (a group of) phenomena, facts, or a scientific inquiry that may be tested, verified or answered by further investigation or methodological experiment.
Scientific Method
the means of science by which phenomena are observed, hypotheses are tested, and conclusions are drawn.
Supernatural
pertains to being above or beyond what is natural, unexplainable by natural law or phenomena
Reproducibility
one of the main principles of the scientific method, and refers to the ability of a test or experiment to be accurately reproduced, or replicated, by someone else working independently
Predictive Power
refers to its ability to generate testable predictions
Naturalism
the world can be understood in scientific terms without recourse to spiritual or supernatural explanations
Uniformitarianism
assumes that the same natural laws and processes that operate in the universe now, have always operated in the universe in the past and apply everywhere in the universe.
Theory
a well-substantiated explanation of some aspect of the natural world
Folk Classification
technical descriptive classification of sedimentary rocks devised by Robert L. Folk
Cladistics
organisms are grouped based upon synapomorphies (shared derived characteristics) only, and not upon symplesiomorphies (shared ancestral characteristics)

Ex Nihilo Creation
"creation out of nothing"
Natural Selection
a natural process resulting in the evolution of organisms best adapted to the environment
Microevolution
refers to evolution that occurs at or below the level of species, such as a change in the gene frequency of a population of organisms or the process by which new species are created
Macroevolution
refers to evolution that occurs above the level of species, such as the origin of new designs (feathers, vertebrates from invertebrates, jaws in fish), large scale events (extinction of dinosaurs), broad trends (increase in brain size in mammals)
TEK
traditional ecological knowledge. Place-based knowledge in which people learn to adapt to their own environment through interactions, observations and experiences with their ecological system
Diachronic
occurring or changing along with time
Synchronic
occurring or existing at the same time or having the same period or phase
