Grade 5 Ecosystems and Food Webs Practice Test

Build Grade 5 Science skills with five 10-question practice tests on ecosystem parts, habitats, producers, consumers, decomposers, food chains, food webs, and environmental changes.

Ecosystems and Food Webs Practice Tests

These Grade 5 Science practice tests help students explain how living and nonliving parts of ecosystems interact. Students identify habitats, populations, producers, consumers, decomposers, food chains, food webs, energy flow, matter cycling, population changes, and human impacts.

Skills covered

  • Identifying biotic and abiotic ecosystem factors
  • Distinguishing habitats, populations, communities, and ecosystems
  • Classifying producers, consumers, and decomposers
  • Reading food chains and connected food webs
  • Tracing energy flow and nutrient cycling
  • Explaining population changes, competition, and adaptations
  • Using evidence to evaluate habitat restoration and human impacts

How to use these practice tests

Start with the organism or factor described. Decide whether it is living or nonliving, identify its role in the food web, and trace what may happen when food, water, shelter, predators, or environmental conditions change.

1. QuestionMultiple choice

What is a producer?

Please select an answer first.

Correct answer: A

The correct answer is An organism that makes its own food, usually using light energy..

  1. Identify the ecosystem role: Decide whether the question describes a living part, nonliving factor, feeding relationship, habitat, or population change.
  2. Trace the relationship: Plants and many algae are producers because they make food using energy from light.
  3. Choose the best explanation: The correct choice is An organism that makes its own food, usually using light energy..

Plants and many algae are producers because they make food using energy from light.

2. QuestionMultiple choice

What is a consumer?

Please select an answer first.

Correct answer: B

The correct answer is An organism that gets energy by eating other organisms..

  1. Identify the ecosystem role: Decide whether the question describes a living part, nonliving factor, feeding relationship, habitat, or population change.
  2. Trace the relationship: Consumers cannot make their own food in the same way producers do, so they obtain energy by feeding.
  3. Choose the best explanation: The correct choice is An organism that gets energy by eating other organisms..

Consumers cannot make their own food in the same way producers do, so they obtain energy by feeding.

3. QuestionMultiple choice

What is a decomposer?

Please select an answer first.

Correct answer: C

The correct answer is An organism that breaks down dead material and returns nutrients to the ecosystem..

  1. Identify the ecosystem role: Decide whether the question describes a living part, nonliving factor, feeding relationship, habitat, or population change.
  2. Trace the relationship: Fungi and many bacteria decompose dead organisms and help recycle matter.
  3. Choose the best explanation: The correct choice is An organism that breaks down dead material and returns nutrients to the ecosystem..

Fungi and many bacteria decompose dead organisms and help recycle matter.

4. QuestionMultiple choice

Which organism is usually a producer in a pond ecosystem?

Please select an answer first.

Correct answer: D

The correct answer is Algae.

  1. Identify the ecosystem role: Decide whether the question describes a living part, nonliving factor, feeding relationship, habitat, or population change.
  2. Trace the relationship: Algae can make food using light, so they are producers.
  3. Choose the best explanation: The correct choice is Algae.

Algae can make food using light, so they are producers.

5. QuestionMultiple choice

Which organism is a consumer?

Please select an answer first.

Correct answer: A

The correct answer is A rabbit eating grass..

  1. Identify the ecosystem role: Decide whether the question describes a living part, nonliving factor, feeding relationship, habitat, or population change.
  2. Trace the relationship: The rabbit obtains energy by consuming grass.
  3. Choose the best explanation: The correct choice is A rabbit eating grass..

The rabbit obtains energy by consuming grass.

6. QuestionMultiple choice

Why are decomposers important?

Please select an answer first.

Correct answer: B

The correct answer is They return nutrients from dead material to soil and other parts of the ecosystem..

  1. Identify the ecosystem role: Decide whether the question describes a living part, nonliving factor, feeding relationship, habitat, or population change.
  2. Trace the relationship: Decomposers recycle matter and make nutrients available for producers.
  3. Choose the best explanation: The correct choice is They return nutrients from dead material to soil and other parts of the ecosystem..

Decomposers recycle matter and make nutrients available for producers.

7. QuestionMultiple choice

Which energy source starts most food chains on Earth?

Please select an answer first.

Correct answer: C

The correct answer is The Sun.

  1. Identify the ecosystem role: Decide whether the question describes a living part, nonliving factor, feeding relationship, habitat, or population change.
  2. Trace the relationship: Producers capture sunlight and use it to make food, beginning many food chains.
  3. Choose the best explanation: The correct choice is The Sun.

Producers capture sunlight and use it to make food, beginning many food chains.

8. QuestionMultiple choice

What do arrows in a food chain usually show?

Please select an answer first.

Correct answer: D

The correct answer is The direction that energy and food move from one organism to another..

  1. Identify the ecosystem role: Decide whether the question describes a living part, nonliving factor, feeding relationship, habitat, or population change.
  2. Trace the relationship: Arrows point from the organism being eaten toward the organism receiving energy.
  3. Choose the best explanation: The correct choice is The direction that energy and food move from one organism to another..

Arrows point from the organism being eaten toward the organism receiving energy.

9. QuestionMultiple choice

Which statement about energy in an ecosystem is correct?

Please select an answer first.

Correct answer: A

The correct answer is Energy moves through organisms, while matter can be recycled..

  1. Identify the ecosystem role: Decide whether the question describes a living part, nonliving factor, feeding relationship, habitat, or population change.
  2. Trace the relationship: Energy flows through food relationships, while decomposers help cycle matter.
  3. Choose the best explanation: The correct choice is Energy moves through organisms, while matter can be recycled..

Energy flows through food relationships, while decomposers help cycle matter.

10. QuestionMultiple choice

Which example shows a decomposer helping a producer?

Please select an answer first.

Frequently asked questions about Grade 5 Ecosystems and Food Webs

What is a food web?

A food web is a group of connected food chains that shows how energy and food move among organisms in an ecosystem.

Why are producers important?

Producers bring energy into many ecosystems by making food, usually with light energy, and support consumers and decomposers.
