Population I
Name one way a population can grow.
More births than deaths; immigration
Population I: 200
Provide two examples of a limiting factor
Predation, disease, natural disaster,
deforestation, etc.
Population I: 300
Which of the following letters would most likely represent exponential
growth? J or S
“J”
Population I: 400
What is meant by carrying capacity?
The maximum number of individuals that an
environment can support
Population I: 500
Explain exponential growth.
Exponential growth refers to growth of a population at a constant rate; only under ideal conditions
Population II: 100
Name and spell the term used to describe the
movement of individuals into an area.
Immigration
Population II: 200
There are 20 white-tailed deer occupying a forest
of 10 square miles. What is the population density
of the deer?
2 deer per square mile
Population II: 300
Explain how a population would achieve a negative
growth rate
More deaths than births
Population II: 400
List and describe the three types of geographic
distribution
1.Random- no order2.Clumped- grouped3.Uniform- orderly; a
pattern; evenly dispersed
Population II: 500
Is disease density-dependent or independent?
Why?
Density-dependent; disease will only become limiting
when the population is large and dense
Succession: 100
Primary Succession occurs when this abiotic
factor is missing.
SOIL
Succession: 200
Name two events that may initiate the process of secondary succession.
Natural Disaster; deforestation
Succession: 300
What is significant of the presence of a climax
community?
Climax communities are a stable group of plants and animals in an area; function optimally until
disturbance
Succession: 400
Explain the process in which a pioneer species, like
lichen, creates soil.
Lichen adheres to the surface of rock, and begins creating cracks (via
the release of acid from photosynthesis); rocks are broken
down, creating soil; death and decay of lichen add nutrients to soil
Succession: 500
Explain how larger, complex plant species come to existence
in an area undergoing ecological succession.
As pioneer species die and decompose, the soil is enriched, allowing for other
plants with the necessary adaptations to grow and develop; they too die and decay further enriching the soil with nutrients-
new plants with the necessary adaptations are able to move into the area, grow and
develop
Biodiversity: 100
The word used to describe the genetic variability of living
organisms
Biodiversity
Biodiversity: 200
What is an endangered species?
A group of organisms near extinction
Biodiversity: 300
Name and describe one effort to protect the Earth’s biodiversity.
National Parks-preservation of habitat and living organisms
Captive Breeding- breeding of endangered species held in
captivity; held until population grows and begins to stabilize;
released into natural environment
Biodiversity: 400Category 4 – 40 Points
Name and describe one way humans interfere with biodiversity
1.Hunting: Death of too many animals limits those genetically viable organisms
which can reproduce2.Deforestation: Loss of
habitat/resources may lead to death of organisms; loss of genetic variability in
gene pool
Biodiversity: 500
Explain the significance of the Earth’s biodiversity.
More biodiversity means the possibility of more medicine; loss of other
resources
Miscellaneous: 100
The name used to describe those factors
that cause a decrease in the size of a population.
Limiting Factors
Miscellaneous: 200
Logistic growth can only occur following a period of this type of growth.
Exponential
Miscellaneous: 300
Name two events that would initiate primary
succession.
Volcanic eruption; Glacial retreat (both exposing
bare rock)
Miscellaneous: 400
Describe what is meant by a density-independent limiting factor. Provide an example.
These factors are limiting to the population regardless of
its size; weather cycles, natural disasters, human
interference
Miscellaneous: 500
Would the introduction of a parasite become limiting to a
small, highly scattered population? Why or why not?
No…parasitism is a density-dependent LF; in order to
become limiting the population would need to be large and
dense
Final Jeopardy
“The Lonliest Animals”
What was the significance of the gate (within the pond) that
separated the male and female rafetus turtles?
