1. QuestionMultiple choice

What is the role of a producer in an ecosystem?

Please select an answer first.

Correct answer: A

The correct answer is It makes its own food, usually using light energy..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Producers such as plants make food and provide energy for other organisms.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Producers such as plants make food and provide energy for other organisms.

2. QuestionMultiple choice

In the food chain grass → rabbit → fox, which organism is the primary consumer?

Please select an answer first.

Correct answer: B

The correct answer is The rabbit.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: A primary consumer eats a producer. The rabbit eats grass.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

A primary consumer eats a producer. The rabbit eats grass.

3. QuestionMultiple choice

What is the role of a decomposer?

Please select an answer first.

Correct answer: C

The correct answer is It breaks down dead matter and returns nutrients to the environment..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Decomposers break down dead organisms and help recycle nutrients.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Decomposers break down dead organisms and help recycle nutrients.

4. QuestionMultiple choice

Why is less energy available at higher levels of a food chain?

Please select an answer first.

Correct answer: D

The correct answer is Organisms use much of the energy for life processes..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Organisms use energy for movement, growth, repair, and other life processes, so less transfers upward.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Organisms use energy for movement, growth, repair, and other life processes, so less transfers upward.

5. QuestionMultiple choice

What is a habitat?

Please select an answer first.

Correct answer: A

The correct answer is The place where an organism lives and obtains what it needs..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: A habitat provides food, water, shelter, and other conditions an organism needs.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

A habitat provides food, water, shelter, and other conditions an organism needs.

6. QuestionMultiple choice

A pond population grows until food becomes scarce. Which factor is limiting the population?

Please select an answer first.

Correct answer: B

The correct answer is The amount of available food.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: A limiting factor restricts population growth. Scarce food limits how many organisms can survive.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

A limiting factor restricts population growth. Scarce food limits how many organisms can survive.

7. QuestionMultiple choice

Which relationship benefits both organisms?

Please select an answer first.

Correct answer: C

The correct answer is Mutualism.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Mutualism is a symbiotic relationship in which both organisms benefit.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Mutualism is a symbiotic relationship in which both organisms benefit.

8. QuestionMultiple choice

What is one possible effect of an invasive species entering a new ecosystem?

Please select an answer first.

Correct answer: D

The correct answer is It may compete with native species for resources..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: An invasive species may use food, space, or shelter that native organisms need.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

An invasive species may use food, space, or shelter that native organisms need.

9. QuestionMultiple choice

Why is matter considered to cycle through an ecosystem?

Please select an answer first.

Correct answer: A

The correct answer is Matter is reused as organisms eat, grow, die, and decompose..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Elements and compounds move between living things and the environment through ecosystem processes.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Elements and compounds move between living things and the environment through ecosystem processes.

10. QuestionMultiple choice

Why can biodiversity help an ecosystem remain stable?

Please select an answer first.

Correct answer: B

The correct answer is Different species can fill different roles and support recovery from change..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: A variety of species provides multiple roles and can make an ecosystem more resilient.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

A variety of species provides multiple roles and can make an ecosystem more resilient.
