Question

Instructions: The Virtual Populations Lab is on the lesson assessment page. Gather data to evaluate Sebastian's Snorkel Spot's claim that a new factory is polluting the coral reef. Follow the instructions as you move through the lab and record your data and observations in the lab report.

Answer 1

The investigation of a coral reef ecosystem in relation to a pollution claim involves creating a detailed representation of organism interactions, constructing a food web, and formulating a hypothesis on species relatedness. A comprehensive plan for data collection focusing on water quality and organism health is essential for evaluating the factory's impact on the coral reef.

Step-by-step explanation:

To investigate the claim that a new factory is polluting a coral reef ecosystem, one must first understand the interactions between organisms in this environment. Selecting a coral reef, you would create a representation showcasing how various organisms like fish, corals, and algae interact with each other and their surroundings. Next, by analyzing these interactions and the similarities and differences among the species, you could formulate a hypothesis about their relatedness. This may include examining physical features, behaviors, or genetic markers.

Further, constructing a food web will clarify each organism's role in the reef. Removing one organism from this web illustrates how interconnected and dependent species are in an ecosystem, and demonstrates the potential far-reaching impacts of pollution on the movement of matter and energy. Similarly, assessing the effects of changes in this web can predict potential disruptions due to the factory's presence.

Finally, to directly address pollution concerns, a plan for data collection should be devised. This plan could involve monitoring water quality, measuring coral bleaching, and tracking the abundance and health of sentinel species over time before and after the factory's operation. Such data would provide concrete evidence to support or refute Sebastian's Snorkel Spot's claim regarding the factory's environmental impact.

Instructions: The Virtual Populations Lab is on the lesson assessment page. Gather data to evaluate Sebastian's Snorkel Spot's claim that a new factory is polluting the coral reef. Follow the instructions as you move through the lab and record your data and observations in the lab report.

Title: Sebastian’s snorkel spot

Objective(s): The objective is to watch the conditions in the coral reef to prove that the factory is polluting the reef.

Hypotheses: If pollution levels increase, then the health of the coral reef with decrease. levels increase, then the health of the coral reef will

Variables:

Dependent- heath of the reef by water clarity, dissolved oxygen, live coral coverage, and stoplight parrot fish population.

Independent- the additional pollution and runoff from the factory

Procedure:

Take measurements or water clarity and dissolved oxygen levels to measure the water around the reef or five? weeks record results

Measure the percent of live coral coverage for five? weeks record results

Count population the fish for five? weeks record results

During the research phase, you found that the factory is not using nutrient-removal treatment on the water it releases. Excess nutrients in the water encourage algae growth, which can smother coral. To monitor the water quality and health of the coral reef, you will collect data on five factors: water clarity, dissolved oxygen levels, percentage of live coral coverage, number of juvenile parrot fish observed, and number of mature parrotfish observed.

Data:

Record your data from the virtual lab in the data table.

Week Water Clarity (m) Dissolved Oxygen Level (mg/L) Percentage of Live Coral Coverage (%) Number of Juvenile Parrotfish Number of Mature Parrotfish

0 6 14:00 35 8 12

1 4 12:00 30 7 12

2 3 10:00 25 7 11

3 3 9:00 25 5 11

4 2 9:00 20 4 9

Data Analysis:

Select one abiotic factor that was monitored, either water clarity or dissolved oxygen level, and create a line graph showing the measurement of the abiotic factor over time. Then select one biotic factor that was monitored, either coral coverage, juvenile parrotfish, or mature parrotfish, and create a line graph showing the measurement of the biotic factor over time.

I cant include this part

Conclusion: I hypothesized that if pollution levels increase, then the health of the coral reef with decrease. My hypothesis was proven correct, the four-week time that had been recorded showed that every week the biotic and abiotic features would decrease. My graph shows the decrease in four weeks due to the factory.

Be sure to answer the following reflection questions as a summary in the conclusion of your lab report:

• Was your hypothesis correct? Why or why not? Be sure to include evidence from the data you collected to support your conclusion.

• Based on your data, describe the overall trend for each of the five factors that were measured?

• What information do your graphs show? Describe the correlation between the two factors that you graphed

Questions:

Using what you have learned in the lesson and the virtual lab activity, answer the following questions in complete sentences:

1. Identify the abiotic and biotic factors in this lab.

The water clarity and the dissolved oxygen level were abiotic and coral coverage, and the fish were biotic.

2. Describe the symbiotic relationship between each of the organisms.

Coral is a habitat for fish and if the coral isn’t in good condition the water most likely isn’t so the fish would decrease.

3. Explain how the limiting factors affect carrying capacity in each population.

Without proper healthy coral the fish would decrease and without livable water the fish will die?
