What’s the difference between density dependent and density independentlimiting factors?
Identify the difference between density dependence anddensity independence.
Read each situation in the chart below. Then, state if it is a density-independent limiting factor or a density-dependent limiting factor. Then, state the specific limiting factor that is occurring. The first one is done for you as an example.
SITUATION
Dependent - Independent or Density-Dependent
Limiting Factor
Mrs. Engelbrecht has 32 students assigned to her Biology Class, but she only has room for 28. Because the room is crowded, the extra 4 students leave room to go to Guidance and have their schedules changed.
Density- Dependent
Emigration
Northern pike (it’s a fish) feed on another fish, the yellow perch. An increase in the yellow perch population causes an increase in the northern pike population.
Density- Dependent
The BP oil spill in the Gulf of Mexico has harmed many aquatic organisms that live in the Gulf region.
Density- Independent
A new strain of influenza (the flu) breaks out in New York City

- The following statements are either true or false. Indicate true or false and justify your answer briefly. An unbiased estimator is said to be consistent if the difference between the estimator and the population parameter grows smaller as the sample size grows larger. An unbiased estimator is a sample statistic whose expected value equals the population parameter. Knowing that an estimator is unbiased neither assures us that its expected value equals the population parameter, nor does it tell us how close the estimator is to the population parameter. A specific confidence interval obtained from sample data will always correctly estimate the population parameter.arrow_forwardList and explain the assumptions and uses of the Hardy-Weinberg Principle.
