(Continue with at least 20 more multiple choice questions covering topics such as population dynamics, toxicology, climate change, land use, water resources, energy resources, pollution control, and sustainable practices.)

Section 2: Free Response Questions

Instructions: Answer the following free-response questions in complete sentences. Each question is worth several points, with points allocated based on the completeness and accuracy of your answers.

1. (Essay Question – approx. 500 words): Describe the process of eutrophication in a lake or pond. Discuss the sources of nutrients that contribute to eutrophication, the ecological consequences of this process, and potential strategies for mitigating its effects. Include specific examples of organisms that are affected and the role of human activity in accelerating this process.

2. (Problem-Solving Question – approx. 250 words): A city is considering two different energy sources to power its new municipal building: solar energy and natural gas. Compare and contrast the environmental impacts of each energy source, considering factors such as greenhouse gas emissions, land use, water use, and air pollution. Recommend which energy source is more environmentally sustainable and justify your recommendation with specific data and evidence.

3. (Data Analysis Question – approx. 250 words): (Provide a data set, such as a graph or table, showing trends in a specific environmental parameter, e.g., CO2 levels, deforestation rates, or species extinction rates). Analyze the data provided and explain the trends observed. Discuss the potential causes of these trends and their implications for the environment. Propose at least one potential solution to address the problem illustrated by the data.

Section 3: Detailed Explanations of Multiple Choice Answers

(Provide detailed explanations for each multiple-choice question, explaining the correct answer and why the other options are incorrect. This section should be comprehensive and informative, helping students understand the underlying principles and concepts.)

For example:

1. Correct Answer: (d) Chlorofluorocarbons (CFCs) CFCs have an extremely high global warming potential, many times greater than CO2, CH4, or N2O. While all these gases contribute to the greenhouse effect, CFCs are particularly potent due to their long atmospheric lifespan and their ability to absorb infrared radiation.

2. Correct Answer: (b) Burning of fossil fuels The burning of fossil fuels releases sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere. These gases react with water vapor to form sulfuric acid and nitric acid, which then fall to the earth as acid rain.
