Species

Ecology
The Study of all processes influencing the distribution and abundance of organisms and the interactions between living things and their environment.
Population
A certain number of individuals that make up interbreeding, reproducing, group.
Biotic Community
The grouping or assemblage of plants, animals, and microbes.
Abiotic
The nonliving, chemical, and physical factors, water, moisture, and climate.
Ecosystems
A grouping of plants, animals, and microbes occupying an explicit unit of space and interacting with their environment.
Ecotone
A transitional area between two adjacent ecosystems that has characteristics of both.
Landscapes
A group of interacting ecosystems.
Biomes
Similar or related to ecosystems or landscapes that are often grouped together.(Only Terrestrial not Aquatic)
Biosphere
All species and physical factors of earth functioning as one unified ecosystem.

Resources
Any factors(biotic or abiotic) that are consumed by organisms.(Water, Nutrients, Oxygen)
Law of Limiting Factors
Every organism has an optimal range, zones of stress, and limits of tolerance.
Optimum
A certain level at which organisms do best
Range of Tolerance
The entire span that allows any growth at all
Limits of Tolerance
Point at the high and low ends of the range of tolerance.
Zones of Stree
Region between optimal range and high or low limits of tolerance
Limiting Factor
A factor that limits growth
Synergistic Effects(Synergism)
Two or more factors interacting in a way that causes an effect much greater than one would anticipate from effects of each of the two acting seperately.
Habitat
Refers to the kind of place where a species is biologily adapted to live.
Ecological Niche
What an animal feeds on, where it feeds, where it lives, where it nests, and how it responds to abiotic factors.
