1. QuestionMultiple choice

What may happen when fertilizer runoff adds too many nutrients to a lake?

Please select an answer first.

Correct answer: A

The correct answer is Algae may grow rapidly and reduce oxygen in the water.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: Excess nutrients can cause algal blooms that change oxygen conditions in the lake.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

Excess nutrients can cause algal blooms that change oxygen conditions in the lake.

2. QuestionMultiple choice

Which evidence best supports the claim that an invasive species affects a food web?

Please select an answer first.

Correct answer: B

The correct answer is Native prey numbers fall after the invasive predator population rises.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: The population pattern connects the invasive predator with a change in native prey.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

The population pattern connects the invasive predator with a change in native prey.

3. QuestionMultiple choice

What does carrying capacity describe?

Please select an answer first.

Correct answer: C

The correct answer is The largest population an environment can support over time.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: Carrying capacity depends on available resources and environmental conditions.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

Carrying capacity depends on available resources and environmental conditions.

4. QuestionMultiple choice

How can a population exceed the carrying capacity temporarily?

Please select an answer first.

Correct answer: D

The correct answer is Resources may support more organisms for a short time before becoming limited.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: A temporary resource increase can allow a population to grow before resources become scarce.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

A temporary resource increase can allow a population to grow before resources become scarce.

5. QuestionMultiple choice

Which action can reduce erosion on a hillside?

Please select an answer first.

Correct answer: A

The correct answer is Planting vegetation and using terraces.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: Roots hold soil, and terraces slow water movement down a slope.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

Roots hold soil, and terraces slow water movement down a slope.

6. QuestionMultiple choice

Why can wetlands reduce flooding?

Please select an answer first.

Correct answer: B

The correct answer is They store and slow moving water.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: Wetlands can temporarily hold water and reduce the speed of runoff.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

Wetlands can temporarily hold water and reduce the speed of runoff.

7. QuestionMultiple choice

A graph shows that a city’s average temperature increased as tree cover decreased. What does the graph suggest?

Please select an answer first.

Correct answer: C

The correct answer is Less tree cover may be associated with higher temperatures.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: The graph shows an association, though more evidence is needed to establish cause.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

The graph shows an association, though more evidence is needed to establish cause.

8. QuestionMultiple choice

Which practice helps conserve freshwater?

Please select an answer first.

Correct answer: D

The correct answer is Repairing leaks and reusing water when safe.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: Reducing waste and preventing pollution helps conserve usable freshwater.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

Reducing waste and preventing pollution helps conserve usable freshwater.

9. QuestionMultiple choice

What is biodiversity?

Please select an answer first.

Correct answer: A

The correct answer is The variety of living organisms in an area.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: Biodiversity includes the variety of species, genes, and ecosystems in a region.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

Biodiversity includes the variety of species, genes, and ecosystems in a region.

10. QuestionMultiple choice

Why should an environmental conclusion include uncertainty when appropriate?

Please select an answer first.

Correct answer: B

The correct answer is Measurements and observations may not explain every factor.

  1. Identify the science idea: Decide whether the question is about cells, matter, energy, Earth systems, ecosystems, design, or evidence.
  2. Use the evidence: Recognizing limits in data makes a conclusion more accurate and open to further testing.
  3. Check the claim: Make sure the answer matches the observation, model, data, or system described.

Recognizing limits in data makes a conclusion more accurate and open to further testing.
