WorksheetsCarrying Capacity and Population
Total questions: 27
Worksheet time: 22mins
What is the carrying capacity of the idealized population graph?
1000
8000
800
600
This may cause a population to increase
increase of food supply
removal of predators
removal of disease
all of these
If the carrying capacity of a predator decreases, what will happen to the carrying capacity of the prey?
Will Increase
Will Decrease
Will stay the same
A scientist was studying a population of fish in a pond over a period of 10 years. They observed that the population increased each year for 3 years, and then remained nearly constant for the rest of the study. The best explanation for this observation is that the population had
stopped reproducing
reached carrying capacity
mutated into a different species
run out of food and all died
What are factors that affect carrying capacity?
Biotic only
Biotic and abiotic
Depends on the ecosystem
Abiotic only
What happens if a population grows past its carrying capacity?
The population is encouraged to include more in their diet
Environmental resistance causes some individuals to die off
The entire species will go extinct
The carrying capacity just increases to accommodate more individuals
'B' represents...
overshoot of the carrying capacity
logarithmic growth
exponential growth
lag phase
What is the carrying capacity of the graph?
around 500
more than 800
less than 300
around 700
(B + I) > (D + E) what does population do?
population increases
population decreases
population stays the same
all of these
When death rate is equal to birth rate...
population increases
population decreases
population stays the same.
population rapidly increases then becomes stable
When the death rate rises and the birth rate lowers...
population increases
population decreases
population stays the same
all of these
When birth rate is high and death rate is low...
population increases
population decreases
population stays the same
all of these
What is carrying capacity?
A condition that occurs when two or more organisms compete for the same resources within an ecological community
A relationship in which two organisms are mutually dependent on each other for survivial
All the biotic and abiotic factors and the interactions among them in a given area
The maximum number of organisms an ecosystem can support
What is ecosystem?
A condition that occurs when two or more organisms compete for the same resources within an ecological community
All the biotic and abiotic factors and the interactions among them in a given area
The maximum number of organisms an ecosystem can support
A relationship in which two organisms are mutually dependent on each other for survival
All the biotic and abiotic factors and the interactions among them in a given area
Interdependent Relationship
Carrying Capacity
Ecosystem
Competition
What type of growth is demonstrated in the graph?
Exponential
Carrying capacity
Linear
Negative
Which of the following demonstrates population growth when there is limited available water in an area?
When Yellowstone National Park was created in the late 1800s, wolves were on the decline. The last wolves in Yellowstone were killed in 1926, but in the 1800s, there were between 100-160 wolves in the park. In 1995, gray wolves were reintroduced to the park.
Which graph (drawn in red) below shows a prediction of how the wolf population would change if there was less water available in the ecosystem?
There would be no change to carrying capacity.
If there are 25 rabbits living in a 5 acre area, what is the population density of the rabbits?
125 rabbits per acre
30 rabbits per acre
20 rabbits per acre
5 rabbits per acre
What type of distribution pattern is evenly spaced apart from one another?
Uniform
Clumped
Random
Uneven
Lag phase occured when?
after generation 11 to generation 30
during 'A'
at 'B' exactly
between generations 1 - 5
(B + I) < (D + E) what does population do?
population increases
population decreases
population stays the same
all of these
When net births is negative (mortality) and net migration is negative the population will
population increases
population decreases
population stays the same
all of these
What does the straight yellow line represent? What is it called?
exponential growth, E line
fluctuation, K line
carrying capacity, K line
environment resistance, R line
