Ecological Impact of Farmland Conversion

What is a potential negative impact of converting a forest near a lake into farmland?

• Increased biodiversity

• Improved water clarity

• Runoff of fertilizers into the lake

• Decrease in soil nutrients

How does the addition of nitrogen and phosphorus affect a lake?

• It increases fish population

• It leads to eutrophication

• It reduces algae growth

• It makes the water clearer

What happens to the water in a lake during eutrophication?

• It becomes clearer

• It evaporates faster

• It becomes cloudier

• It remains unchanged

What is the effect of increased decomposers on oxygen levels in a lake?

• Oxygen levels fluctuate

• Oxygen levels decrease

• Oxygen levels increase

• Oxygen levels remain the same

Why might a non-native fish species become dominant in a lake affected by eutrophication?

• They reproduce faster

• They are larger in size

• They are more colorful

• They are more tolerant to reduced oxygen
