|
The study of the interactions between organisms and the living and nonliving components of their enviornment.
|
|
Green house effect?
|
When carbon dioxide and water vapor intercept the reflected heat and direct it back toward earth. it insulates earth from the deep freeze of space.
|
|
The levels of organization are:
|
Biospehere, ecosystrem communtiy population organism (BECPO)
|
|
Biosphere is:
|
the thin volume of earth and its atmoshphere that supports life. all organisms are found within this.
|
|
an ecosystem is:
|
biosphere is composed of smaller units called ecosystems. which inclues all of the organims and the nonliving enviornment found in a particular place. consider a pond an ecosystem.
|

|
|
Biotic Factors
|
living components of the environment.
|
|
Abiotic Factors
|
the nonliving components of the environment.
|
|
Tolerance curve:
|
a graph o fperformance versus values of an eviornmental variable, such as temperature.
|
|
Acclimation:
|
siome organisms can adjust their tolerance to abiotic factors through this process.
|
|
Confomers
|
organims that do not regulate their internal conditions, they cahnge as their external enviornment changes.
|
|
Regulators
|
are organims taht use energy to conrol some of their internal conditions.
|
|
dormance
|
a sate of reduced activity
|
|
migration
|
to move to another, more favorable habitat.
|
|
reources
|
the entergy and materials teh species needs.
|
|
niche
|
a species way of life
|
|
fundamental niche
|
the range of conditions that a species can potentially tolerate the range of resrounces it can petentially use.
|
|
realized niche
|
the range of resources it actually uses.
|
|
generalist
|
species with boad niches.
