Migration - ANSWER--a regular long-distance change in
location. Animals often use environmental cues to guide
this behavior.
Density-dependent factors of population growth -
ANSWER--a birth rate that decreases or a death rate that
increases with rising population density is influenced by
these factors. the mechanisms for this: competition for
resources, disease, predation, territoriality (causes space
to become a resource for which individuals compete),
,intrinsic factors (some organism's fertility rates drop as a
result of the stress causes by antagonistic interactions
with members of its own species), and toxic wastes (some
organisms produce byproducts that, if they accumulate
enough, can be toxic to them)
Density-independent factors of population growth -
ANSWER--a birth or death rate that does not change with
population density is influenced by these factors.
Demographic transition in human populations - ANSWER--
the movement from high birth rates and death rates to low
birth rates and death rates in human populations;
generally accompanies industrialization and improved
living conditions; is associated with an increase in the
, quality of healthcare and sanitation as well as improved
access to education (especially for women)
Tropical forest - ANSWER--A type of biome that typically
occurs in equatorial and subequatorial regions. Can have
relatively constant (rain type) or highly seasonal (dry type)
precipitation. Has high temperatures year-round. Are
vertically layered and competition for light is generally
intense. Has the most animal diversity of any other
terrestrial biome.
Desert - ANSWER--A type of biome that typically occurs in
bands near 30* north and south latitudes. Characterized
by extremely low, highly variable precipitation.
Temperatures can be extremely variable depending on the
