Which of the following activities is a human impact on the carbon cycle that contributes to climate change?

• When excess carbon dioxide is absorbed by the oceans, a chemical reaction occurs that lowers the pH of the water.

• If carbon-based fertilizer is applied to farmland, fertilizer can produce greenhouse gases.

• Acid rain results in greenhouse gas emissions in the atmosphere, worsening climate change.

• When humans cut down trees, less carbon is captured in forests, leaving more in the atmosphere and amplifying climate change.

What is the difference between artificial eutrophication and natural eutrophication?

• Artificial eutrophication is caused by fertilizer, while natural eutrophication is caused by cleaning products.

• Artificial eutrophication is caused by cleaning products, while natural eutrophication is caused by fertilizer.

• Artificial eutrophication is a slow process, while natural eutrophication happens much more quickly.

• Artificial eutrophication is caused by humans, while natural eutrophication is caused by a buildup of nutrients over time.

• photosynthesis

How does acid rain impact aquatic ecosystems?

• Acid rain increases the temperature of water, making it difficult for aquatic organisms to survive.

• Acid rain decreases the temperature of water, making it difficult for aquatic organisms to survive.

• Acid rain increases the pH of water, making it difficult for aquatic organisms to survive.

• Acid rain decreases the pH of water, making it difficult for aquatic organisms to survive.

How does eutrophication lead to fish kills?

• Eutrophication causes algae blooms, which fish then ingest thinking it is food, causing their deaths.

• Eutrophication causes algae blooms on the surface of water. When the algae dies, decomposition uses up dissolved oxygen in the water, causing fish death.

• Eutrophication causes algae blooms, which disrupt the food web in the ecosystem, leading to fish kills.

• Eutrophication causes algae blooms, which block out the sunlight from the water. This decreases water temperature, resulting in fish kills.
