Living factors
Nonliving factors
The movement of individuals away from their areas of origin or centers of high population density
Climate patterns on the global, regional, and local level
Very fine climate patterns, such as those encountered by the community of organisms under a fallen log
The long term prevailing weather conditions in a particular area
Regions that lie between 23.5° north latitude and 23.5° south latitude
Major terrestrial or aquatic life zones, characterized by vegetation type or physical environment
Zone in aquatic biomes where there is sufficient light for photosynthesis
Zone in aquatic biomes where little light penetrates
The zone at the bottom of all aquatic biomes
The communities of organisms that make up the benthic zone
A major food source for many benthic species
In the ocean, the part of the benthic zone that lies between 2,000 and 6,000 m below the surface
In the ocean and in most lakes, a narrow layer of abrupt temperature change that separates the more uniformly warm upper layer from more uniformly cold deeper waters
This process brings oxygenated water from a lake's surface to the bottom and nutrient rich water from the bottom to the surface
Lakes which are nutrient-poor and generally oxygen-rich
Lakes which are nutrient-rich and often depleted of oxygen in the deepest zone in summer and covered in ice during the winter.
