### beginning | cause | factor:

Abiotic factor
* affect the ability of organisms to survive and reproduce
  - types of life that are able to survive in a particular ecosystem
* are all non-living parts of the habitat
  - geological, geographical, hydrological and climatological parameters
  - just as important to ecosystems as living components
  - non-living parts of a given ecosystem
  - physical forces such as wind, lightning, fire and people
* are the aspects of the environment
  - most likely culprits for mass extinctions
  - non living parts of an ecosystem
* are the non-living components of an ecosystem
  - factors and biotic factors are the living factors of a habitat
* are the nonliving aspects
  - water, minerals, sunlight, air, climate, and soil
* non-living thing that influences an organism.
* physical or nonliving factor that shapes an ecosystem.
* refer to non-living physical and chemical elements in the ecosystem.

Additional factor
* Some additional factors associate with nutrition.
* are important for regeneration of striated muscle, including stem cells.
* can play a role in a woman's risk for breast cancer.
* include cost.
* include high cost
  - production cost
  - water
* influence behavior
  - feed behavior

Anatomic factor
* can also be responsible for running injuries.
* work in another way.

Antidiuretic factor
* Some antidiuretic factors reduce secretion
  - tubule secretion
* are less well studied than diuretic factors.

Biological factor
* Many biological factors contribute to disperse the larvae on the pasture.
* Some biological factors affect excretion.
* can also cause depression.
* determine sexual orientation.
* influence distribution.
* involve information about target pests on each site or crop.
* play their significant roles very early in a tree's life cycle.
* seem to play a major role in producing Bipolar Affective Disorder.

### beginning | cause | factor:

Biotic factor
* More biotic factors includes all of the native plants that inhabits the taiga biome.
* Most biotic factors affect communities.
* Some biotic factors affect germination
  - habitat selections
  - success
  - populations of organisms
* are all the living parts of a habitat
  - organisms that share an environment
  - also capable of affecting plant growth
  - diseases and insects
  - influences on organisms in an ecosystem
* are the influences on an organism due to the presence of other organisms
  - living aspects of the ecosystem in which an organism lives and part of
* are the living components in the ecosystem such as animals and plants
  - of an ecosystem
  - factors that affect an organism
  - things in the ecosystem
* determine distribution.
* include presence.
* refer to both animals and plants.

Certain factor
* affect capacity
  - connective tissue
  - likelihood
* promote development.

Climatic factor
* Some climatic factors affect abundances
  - bats
  - erosion
* Some climatic factors govern erosion
  - soil erosion
* are responsible for the deterioration of the surface of the stones.
* can affect the abundance of flowering and thus indirectly of seed production
  - damage red alder
* preclude Estonia from becoming a major source for narcotic crops.
* provide habitats
  - suitable habitats

Cognitive factor
* Some cognitive factors affect development
  - personality development
* mediate the effects of the situation and reinforcers.

Common factor
* have air resistance
* influence health.

Complex factor
* Many complex factors affect a compound's rate of action in the human body.
* influence how and why new knowledge affects people's practice.

Conversion factor
* allow one quantity to be expressed on more than one scale of measurement.
* are factors
  - ratios that describe the relationship of one unit to another

Critical factor
* Some critical factors determine the carrying capacity for humans on earth.
* affect decisions
  - quality
* influence cost
* threaten survival.
