10% Rule
Each trophic level in an ecosystem contains about ten percent of the energy of the level below it, due to the inefficient processes of transferring the energy.
Abiotic
A term used to describe something that is not living.
Ammonia
The compound which can be naturally produced by bacteria and then used by nitrogen fixing bacteria and plants. The nitrogen is used to build cells. NH3
Biogeochemical Cycle
Biome
Biotic
Cellular Respiration
Commensalism
A type of interaction between two species in which one species benefits and the other is unaffected.
Community
the grouping of all the animal and plant species that live in a given ecosystem.
Competition
When two species or individuals within an ecosystem must share a limited resource.
Constants/Controlled Variables
Control Group
Decomposition
Ecology
The study of how living things interact with each other and the environment.
Ecosystem
All of the living and non-living things in a given area.
Food Chain
Food Web
GPP
Groundwater
Histogram
Hydrologic Cycle
Independent/Dependent Variable
Laws of Thermodynamics
Mutualism
A type of interaction between two species in which both species increase their chances of survival or reproduction significantly.
Nitrogen Fixation
NPP
Null Hypothesis
Nutrient
Parasitism
A type of interaction between two species in which one species lives in or on the host which they consume to live and reproduce.
Photosynthesis
The process by which plants take sunlight, water, and CO2 and convert it into glucose and O2. The glucose is then used in the plant for energy.
Population
All of the individuals of a given species in a given area.
Positive/Negative Feedback loops
Primary Productivity
Producer
Qualitative Data
Data in the form of qualities, ie color, patter, smell etc.
Quantitative Data
Data in the form of numbers, ie number of teeth, height, weight etc.
Reservoir
Resource Partitioning
The process by which species avoid competition with one another over a given resource through some adaptation through natural selection. Temporal, hunting or flowering at different times, Spatial, inhabiting different areas, Morphological, evolving some physical change.
Salinity
How much salt is in water
Scatterplot
Sink
Source
Symbiosis
When two species interact closely with each other on a long-term basis.
System
Trophic Level
The tiers of a food chain. Primary producer, primary consumer, secondary consumer etc.
Turbidity
Uptake
