# Term Definition
1 flowing bodies of water that start Streams
as freshwater springs or seeps,
flow down slope, and merge into
rivers.
2 a deep zone of a body of water, profundal zone
such as an ocean or a lake,
located below the range of
effective light penetration.
3 The ocean’s bottom formed of benthic province
sediments and rocks. No
penetrating light so rganisms live
in continual darkness, and
organic material from above is
the basis of detrital food chains
4 of a population, the number of Age structure
individuals in each of several age
categories
5 a group of organisms of the Population
same species who live in a
specific location and breed with
one another more often than
they breed with members of
other populations.
6 ratio of males to females in a sex ratio
population.
7 when individuals leave a emigration
population
8 ??? Per capita growth rate
9 Maximum number of individuals Carrying capacity
of a species that an environment
can sustain (k)
10 Has a greater effect in dense Density-dependent
populations than less dense ones
Example: disease, parasites

# Term Definition
11 Area of Earth’s surface required Ecological footprint
to sustainably support one’s level
of development and
consumption
12 Statistics that describe a demographics
population
13 childbirths per 1,000 people per birth rate
year
14 ??? linear growth
15 maximum pop’n growth under biotic potential
ideal circumstances
16 Age-specific traits like age at first life history pattern
reproduction, number of
breeding events, length of
reproductive stage, age of
normal mortality
17 total number of individuals in a population size
population; estimated by
scientists using plot sampling,
and mark-capture sampling
18 Of a population, all individuals reproductive base
who are of reproductive age or
younger
19 deaths per 1,000 people per year death rate
20 a population grows by a fixed exponential growth
percentage in successive time
intervals; the size of each
increase is determined by the
current population size. "J Curve"

# Term Definition
21 a necessary resource, the limiting factor
depletion of which halts
population growth; divided into
two categories:
density-dependent and
density-independent
22 graph showing the decline in survivorship curve
numbers of a cohort over time
23 number of individuals per unit population density
area
24 when new individuals enter a Immigration
population
25 for some interval, the added per capita growth rate
number of individuals divided by
the initial population size
26 a population grows slowly, then logistic growth
increases rapidly until it reaches
carrying capacity and levels off.
"S Curve"
27 Happens regardless of density-independent
population density
28 Individuals who produce a r-selection
maximum number offspring as
quickly as possible have a
selective advantage. Occurs
when population density is low
and resources are abundant.
29 Individuals who produce K-selection
offspring that outcompete others
for limited resources have a
selective advantage. Occurs
when a population is near
carrying capacity
30 where an organism lives and Habitat
reproduces
