C1-100-The answer is…
How do you calculate population
density?
Number of organisms/area
Back
3
C1-200-The answer is…
When organisms move out of a
population it is called
emigration
Back
4
C1-300-The answer is…
What is happening if a population
decreases?
Birth rate is lower than death rate
Back
5
C1-400-The answer is…
What are 2 ways a population can
decrease in size?
Emigration, increased death rate
Back
6
C1-500-The answer is…
Exponential growth occurs when
There are unlimited resources
Back
7
C2-100-The answer is…
In a logistic growth curve, exponential
growth is the phase in which the
population
Grows quickly
Back
8
C2-200-The answer is…
A biotic or abiotic factor that causes
populations to decrease is a
Limiting factor
Back
9
C2-300-The answer is…
This is the population that a given
environment can support
Carrying capacity
Back
10
C2-400-The answer is…
Which would be least likely to be
affected by a density dependent factor?
A small scattered population
Back
11
C2-500-The answer is…
About 500 years ago the population
started to
Increase rapidly
Back
12
C3-100-The answer is…
What caused the human population to
increase dramatically in the last 500
years?
Industrial revolution
Back
13
C3-200-The answer is…
Under ideal conditions with unlimited
resources a population will…
Grow exponentially
Back
14
C3-300-The answer is…
Competition, predation, and parasitism
are all?
Density dependent factors
Back
15
C3-400-The answer is…
What kept the human growth rate low
before the industrial revolution?
Sickness, poor hygiene, low
availability of resources
Back
16
C3-500-The answer is…
What is the difference between an age
structure diagram of a developed
country vs. a developing country?
Developing country – more triangular
Developed country – more even
distribution
from bottom to top
Back
17
C4-100-The answer is…
On a survivorship curve a Type 1
organism might be a?
human
Back
18
C4-200-The answer is…
On a survivorship graph a type 2
organism might be a?
squirrel
Back
19
C4-300-The answer is…
A type 3 curve on a survivorship graph
might include this organism.
Any insect
Back
20
C4-400-The answer is…
In what ways can a population change?
Emigration, immigration, low or high
birth rate or death rate
Back
21
C4-500-The answer is…
What is the difference between
exponential and logistical growth?
Exponential – unlimited quick growth
Logistical – level population rate
because of carrying capacity and
limiting
factors
Back
22

This type of dispersion would be
represented by packs or schools.
clumped
Back
23
C5-200-The answer is…

uniform
Back
24
C5-300-The answer is…
This type of dispersion could be
represented by plants but is rare.
random
Back
25
C5-400-The answer is…
Carrying capacity includes but is not
limited to the following factors.
Amount of available food and living
space
Back
26

The predator-prey relationship is a
density _________ factor.
dependent
Back

Final Jeopardy
Explain the difference between an r-selected organism and a k-selected
organism.
R- selected: short life span, small body size, reproduce
quickly, have many young, little parental care
ex. Cockroaches, weeds, bacteria
K-selected: long life span, large body size, reproduce
slowly, have few young, provide parental care
ex. Humans, elephants
