Organization of natural systems
A living organism, such as a plant, animal, fungus, or bacterium
A biotic factor
Describes how far north or south an area is from the equator. (measured in degrees)
Latitude
The geographic area where an organism occurs throughout its lifetime.
Organisms range.
A group of individuals from the same species, living in the same general area.
Population
Its job/ role in an ecosystem.
A non-living part of the environment, such as sunlight, temperature, precipitation, or humidity
Abiotic factor
Temperature tends to ______ with latitude (When latitude gets higher)
Decrease
An organism’s ________ is its ability to survive variation in abiotic factors, such as changes in temperature or sunlight.
tolerance
A population’s ______ refers to the number of individuals within a specific area.
density
How do we denote Carrying capacity?
K

Precipitation also tends to _______ as latitude gets higher.
Decrease
Each organism has a tolerance range for every abiotic factor in its environment. List the three tolerance ranges (Think about the tolerance graph)
A population can also show different types of ______, which describes how individuals are spread throughout their habitat.
dispersion
Name the two most important abiotic factors when we are talking about climate.
Includes all living organisms in a particular area along with the non-living parts of that environment
Ecosystem.
Latitude can explain global trends in the distribution and number of species. The number of different species in an area is known as what??
species richness
Represents the environmental conditions in which an organism could exist.
fundamental niche
Name the three kinds of dispersion we use when describing populations.
Clumped, uniform, random.
