2.1 Flashcards
Define Population
A group of individuals of the same species in the same area simultaneously.
Define Population Density
The number of Organisms in a given area that can affect the population due to competition for resources, such as predation and the spread of disease.
Define Population Distribution
The spatial pattern is due to the distributing population.
What are the differences between Uniform, random, and clumped? Provide examples.
Uniform is where an object is more or less than space out. For example . . . . . . . .
Random is there are no particular patterns for the object. For example . . .. . .. . . .. .
Clumped is when an object is clustered into groups. For example ……..
Why are population are in one of the three distribution squares?
The population is either uniform, random, or clumped.
What is the population density if two thousand pine trees are over an area of ten square miles?
200 pine trees/square mile
Predict how much grass is on a football field. 100 grass per square in it counts.
57,600 is how big a football field is so there would be 100/1 x/57,600
There would be 5,760,000 grass on the football field.
- Using Mark and recapture, what is the amount of foxes in this forest?
10 were marked - Cpature 5, 2 mark
- Capture 7, 1 mark
- Capture 9, 4 mark
- Capture 5, 0 mark
26 total capture 7 recaptures are marked.
7/26= 10/x
260=7/x
x= 37 total foxes.
Using the answer from problem 8, what are the population density and distribution if the forest is over 10 square miles?
Population distribution is random.
Population density 3.7 foxes per square mile.
What factors a population?
Abiotic, Biotic, and Intrinsic factors.
Define scientific goal
Understanding the factors that influence the size of a population.
Define tactical goal
Management of population. increase, decrease, or maintain the population size.
