Results from the sunflower random sampling activity

Reference no: EM13239216

1. Review the results from the sunflower random sampling activity. a.According to the random sampling method, how many sunflowers were in the plot? (2 points)b. According to the actual count, how many sunflowers were in the plot?

2. Briefly explain why biologists use sampling, rather than counting all members of the population of interest.
3. a. When using random sampling techniques, which type of dispersion is most effective? In other words, which dispersion model will give the most accurate estimation of population size? (2 points)b. Briefly explain why this would be the case.
4. In a forest that measures 5 km by 5 km, a sample was taken to count the number of silver maple trees. The number of trees counted in the grid is shown above. The grids where the survey was taken were chosen randomly. Determine how many silver maple trees are in this forest using the random sampling technique.:

5. Refer to Part B of the procedure (population density).a. List the two locations visited for the procedure. (2 pts)b. Which location had the higher population density of weeds? (1 pts)c. Provide an explanation for why the location listed in question 5b had a higher population density of weeds.

6. What physical and biological factors control the population density of each type of plant in location 1?

7. Returning to the exact same plot six months later, would the population densities of either plant change? Explain.
8. What methods would be used to estimate animal populations? Why? (5 points)--Answer below:

9. From the yeast count activity, predict what the population count for yeast would be at 200 hours. Provide an explanation for the population count prediction (e.g. how did the student arrive at this count?)

10. What is the name of the type of growth yeast exhibit?

11. Is yeast an r-selected or K-selected species?

12. List four factors yeast exhibit which are characteristic of the type of selection they exhibit (see response for Question 11 above).

13. List five factors that influenced the population growth of the yeast in the container. Make sure to include factors with a negative and positive influence, if applicable.:

14. On day three, half of the yeast population was removed from the container and placed in a second container. An additional 2 grams of sugar were added to each container. Describe what the expected growth rate would be for each container.

15. What is the general relationship between population growth and the increase or decrease of resource use?

16. Give two examples of density-dependent limiting factors.

17. Explain why population growth in the human population does not seem to be affected by limiting factors.

18. (Application): How might the information gained from this lab pertaining to Population Ecology be useful to the student or how can the student apply this knowledge to everyday life as a non-scientist?
