3
C1-100-The answer is…
How do you calculate population density?
Number of organisms/area
Back
4
C1-200-The answer is…
When organisms move out of a population it is called
emigration
Back
5
C1-300-The answer is…
What is happening if a population decreases?
Birth rate is lower than death rate
Back
6
C1-400-The answer is…
What are 2 ways a population can decrease in size?
Emigration, increased death rate
Back
7
C1-500-The answer is…
Exponential growth occurs when
There are unlimited resources
Back
8
C2-100-The answer is…
In a logistic growth curve, exponential growth is the phase in which the population
Grows quickly
Back
9
C2-200-The answer is…
A biotic or abiotic factor that causes populations to decrease is a
Limiting factor
Back
10
C2-300-The answer is…
This is the population that a given environment can support
Carrying capacity
Back
11
C2-400-The answer is…
Which would be least likely to be affected by a density dependent factor?
A small scattered population
Back
12
C2-500-The answer is…
About 500 years ago the population started to
Increase rapidly
Back
13
C3-100-The answer is…
What caused the human population to increase dramatically in the last 500 years?
Industrial revolution
Back
14
C3-200-The answer is…
Under ideal conditions with unlimited resources a population will…
Grow exponentially
Back
15
C3-300-The answer is…
Competition, predation, and parasitism are all?
Density dependent factors
Back
16
C3-400-The answer is…
What kept the human growth rate low before the industrial revolution?
Sickness, poor hygiene, low availability of resources
Back
17
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 topBack
18
C4-100-The answer is…
On a survivorship curve a Type 1 organism might be a?
human
Back
19
C4-200-The answer is…
On a survivorship graph a type 2 organism might be a?
squirrel
Back
20
C4-300-The answer is…
A type 3 curve on a survivorship graph might include this organism.
Any insect
Back
21
C4-400-The answer is…
In what ways can a population change?
Emigration, immigration, low or high birth rate or death rate
Back
22
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 factorsBack
23
C5-100-The answer is…
This type of dispersion would be represented by packs or schools.
clumped
Back
24
C5-200-The answer is…
This type of dispersion would be represented by penguins
uniform
Back
25
C5-300-The answer is…
This type of dispersion could be represented by plants but is rare.
random
Back
26
C5-400-The answer is…
Carrying capacity includes but is not limited to the following factors.
Amount of available food and living space
Back
27
C6-500-The answer is…
The predator-prey relationship is a density _________ factor.
dependent
Back
28
Final JeopardyExplain 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
