02.02 Limiting Factors lab



Objective(s):

In your own words, what was the purpose of this lab?



Hypothesis:

In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.


If predators are increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.


If pollution is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.


If the amount of food available is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.



Procedure:

The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable), outcome variable (dependent variable), and control group for this experiment.


Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation. The control group is the group in the experiment where the factors being tested are not applied. It allows scientists to set a baseline to compare the experimental groups that do have factors applied to them.


Test variable (independent variable):


Outcome variable (dependent variable):


Control group:



Data:

Record your data from each trial in the data chart below:


Type of Factor Beginning Frog Count Simulation 1 (Low) Simulation 2 (High)

Predators (alligators)

Pollution

Food (mosquitoes)

Graphs

Use the graphs you printed from the data chart in the virtual lab and analyze the data. Make a note of any trends that you discover.


Predators (alligators):

Pollution:

Food (mosquitoes):



Conclusion:

Your conclusion will include a summary and an interpretation of the lab results. Please write in complete sentences.


Which limiting factor(s) in this lab simulation are biotic?


Which limiting factor(s) in this lab simulation are abiotic?



Which limiting factor im pacted the cricket frog population the most? Use evidence to support your answer.


Which limiting factor impacted the cricket frog population the least?


Use evidence to support your answer.

Mosquitoes can carry and transmit disease to animals and humans. Explain how the cricket frog plays an important role in limiting the spread of mosquito-borne illnesses like West Nile virus and malaria.

Predict the long-term effects of these limiting factors on the cricket frog population in the pond ecosystem.

Sorry I didn't answer the control group one

Answer:

Objective(s): (3 pts)

Despite the superior intellect of our lab workers, none of the problems above actually caused the discrepancies. This occurs sometimes with unexpected or unexplained results, where multiple hypotheses can explain the cause of the discrepancy occur. Here is a challenge: closely examine each video, and see if you are more observant than our lab workers by determining the actual source of the error.

1. How many zebra mussels were there in the Hudson River within a year of their first appearance? A. 500 billion B. 500 million C. 500 thousand D. 500
2. This text explains a cause-and-effect pattern in the Hudson River ecosystem that began with the zebra mussel invasion. What effect did the zebra mussels have on the phytoplankton in the Hudson River? A. The number of phytoplankton in the river rose by a little. B. The number of phytoplankton in the river fell by a little. C. The number of phytoplankton in the river rose by a lot. D. The number of phytoplankton in the river fell by a lot.
3. Phytoplankton are one of the most important parts of the food web in the Hudson River. What evidence supports this conclusion? A. The population of phytoplankton dropped sharply soon after zebra mussels invaded the river. B. The decrease in phytoplankton caused a decrease in the river's zooplankton, fish, and native mussel populations. C. The decrease in phytoplankton meant that the river's turbidity, or cloudiness, decreased. D. Zebra mussels caused oxygen levels in the river to drop, partly by removing the phytoplankton that produce oxygen.
4. Which population was helped by the invasion of the zebra mussels? A. phytoplankton B. zooplankton C. water celery D. native mussels
5. What is the main idea of this text? A. In the years right after the invasion, zebra mussels evolved and adapted to the Hudson River ecosystem. B. In the years right after the invasion, zebra mussels caused a number of changes in the Hudson River ecosystem and food web. C. In the years right after the invasion, zebra mussels did not have a major impact on the Hudson River ecosystem or food web. D. At first, zebra mussels did not have any impact on the Hudson River ecosystem, but their impact increased over time.
6. Read these sentences from the text. "In the years right after the invasion, phytoplankton fell by 80 percent. Zooplankton (which eat phytoplankton) declined by half. And the smallest zooplankton (called microzooplankton), fell by about 90 percent." Based on these sentences, what does the word "decline" most nearly mean? A. to drop in number B. to fall over C. to increase D. to stay the same
7. Choose the answer that best completes the sentence. With far less phytoplankton, the water got clearer. ______, rooted aquatic plants such as water celery increased by up to 40 percent. A. In contrast B. However C. As a result D. Similarly
8. What are two populations that decreased as an immediate result of the zebra mussel invasion?
9. One direct effect of the zebra mussel invasion was a decrease in the cloudiness of the water. How did this affect species in the Hudson River ecosystem?
10. Once scientists understood the short-term impact of the zebra mussel invasion, they started to wonder about the invasion's long-term impact on the ecosystem. Why might the Hudson River ecosystem look different many years after the zebra mussel invasion than it did just a few years after the invasion? Use evidence from the text to support your answer.
