Odds & Ends
100
This is the number of organisms per unit area.
What is population density?
100
List 3 things that affect population change
What is birth rate, death rate, and life expectancy (or immigration/emigration)?
100
This is the number of members added to a population by movement into it.
What is immigration?
100
All organisms in the same type in the same area are a
Population
100
Plant seeds that blow in the wind probably exhibit this type of dispersion pattern.
What is random?
200
Penguins evenly space their nests and protect them from other penguins. Penguins provide an example of this type of dispersion.
What is uniform?
200
the amount by which a population’s size changes over a given time period
What is growth rate?
200
An S-curve is also known as this type of growth.
What is logistic growth?
200
The number of individuals the environment can support over a long period of time.
What is carrying capacity?
200
This is the carrying capacity of this population.
What is 2000?
300
This is the dispersion pattern of birds that flock together and fish that form schools.
What is clumped?
300
What happens when birth rate is greater than death rate?
What is population increase?
300
This is limited by the available energy, water, oxygen and nutrients.
What is carrying capacity?
300
Random sampling (such as calculating # of trees in a forest by counting # in an area and multiplying) works best for this type of dispersion pattern.
What is uniform?
300
Oak trees show this type of survivorship pattern.
What is type III?
400
Solitary animals follow this type of dispersion pattern.
What is random?
400
what occurs when the size of a population becomes larger than the carrying capacity of its ecosystem
What is overpopulation?
400
The rate of population increases greatly during this type of growth.
What is exponential?
400
Technique in which random parts of an area are sampled and averaged to calculate the total population of an area.
What is random sampling?
400
Draw a logistic growth curve and include carrying capacity.
500
If an aquarium holds 80L of water and contains 170 guppies, what is the approximate density, per L, of the guppy population?
What is 2 guppies/L?
500
As population density increases, this increases within the population as organisms try to get the resources they need.
What is competition?
500
If it weren't for this, populations would continue to grow exponentially.
What is the carrying capacity? OR limiting factors?
500
If these were the age structure diagrams of a population of koalas and you were worried about their decline, this population would warrant the most care and concern. (1st, 2nd, or 3rd)
What is the 3rd population?
500
FINAL JEOPARDY: If a country has a growth rate of 10% and there are currently 300 people, what will the population be in 3 years?
300 * .1 = 30 + 300 = 330
330 * .1 = 33 + 330 = 363
363 * .1 = 36.3 + 363 = 399.3
