Environmental Science Practice Tests

These Grade 11 Science practice tests examine ecosystems, populations, succession, nutrient cycles, climate change, pollution, renewable and nonrenewable resources, sustainability, conservation, environmental justice, and data analysis.

Skills covered

  • Analyzing ecosystems, food webs, limiting factors, succession, niches, biodiversity, and invasive species
  • Explaining carbon, nitrogen, and water cycles, greenhouse gases, albedo, ocean acidification, and climate feedbacks
  • Comparing energy resources, life-cycle impacts, sustainability, recycling, commons, and environmental justice
  • Evaluating climate mitigation and adaptation, conservation corridors, pollution, and resource trade-offs
  • Interpreting controls, sampling, correlation, causation, uncertainty, units, and environmental data

How to use these practice tests

Define the environmental system and time scale first. Identify the relevant evidence, distinguish correlation from causation, and consider trade-offs, uncertainty, and effects on future generations.

1. QuestionMultiple choice

What is an ecosystem?

Please select an answer first.

Correct answer: A

The correct answer is A community of organisms and the nonliving environment interacting together.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: An ecosystem includes living communities and abiotic factors such as water, soil, climate, and energy flow.
  3. Check scale and evidence: The correct answer is A community of organisms and the nonliving environment interacting together.

An ecosystem includes living communities and abiotic factors such as water, soil, climate, and energy flow.

2. QuestionMultiple choice

What is a limiting factor?

Please select an answer first.

Correct answer: B

The correct answer is A resource or condition that restricts population growth.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Food, water, space, disease, temperature, and predation can limit population size or distribution.
  3. Check scale and evidence: The correct answer is A resource or condition that restricts population growth.

Food, water, space, disease, temperature, and predation can limit population size or distribution.

3. QuestionMultiple choice

What is a keystone species?

Please select an answer first.

Correct answer: C

The correct answer is A species with an unusually large effect on ecosystem structure relative to its abundance.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Removing a keystone species can cause changes that spread through a food web and alter community structure.
  3. Check scale and evidence: The correct answer is A species with an unusually large effect on ecosystem structure relative to its abundance.

Removing a keystone species can cause changes that spread through a food web and alter community structure.

4. QuestionMultiple choice

What is ecological succession?

Please select an answer first.

Correct answer: D

The correct answer is The gradual change in community composition over time.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Succession describes predictable community changes after disturbance or during development of a habitat.
  3. Check scale and evidence: The correct answer is The gradual change in community composition over time.

Succession describes predictable community changes after disturbance or during development of a habitat.

5. QuestionMultiple choice

What is primary succession?

Please select an answer first.

Correct answer: A

The correct answer is Community development on a surface without preexisting soil.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Primary succession begins on newly exposed surfaces such as bare rock, where soil must develop before many plants can grow.
  3. Check scale and evidence: The correct answer is Community development on a surface without preexisting soil.

Primary succession begins on newly exposed surfaces such as bare rock, where soil must develop before many plants can grow.

6. QuestionMultiple choice

What is secondary succession?

Please select an answer first.

Correct answer: B

The correct answer is Community recovery after disturbance when soil remains.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Because soil, seeds, roots, or organisms remain, secondary succession is usually faster than primary succession.
  3. Check scale and evidence: The correct answer is Community recovery after disturbance when soil remains.

Because soil, seeds, roots, or organisms remain, secondary succession is usually faster than primary succession.

7. QuestionMultiple choice

What is a food web?

Please select an answer first.

Correct answer: C

The correct answer is A network of interconnected food chains.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Food webs represent multiple feeding relationships and show that most organisms have more than one energy pathway.
  3. Check scale and evidence: The correct answer is A network of interconnected food chains.

Food webs represent multiple feeding relationships and show that most organisms have more than one energy pathway.

8. QuestionMultiple choice

What is an ecological niche?

Please select an answer first.

Correct answer: D

The correct answer is A species' role, resource use, and interactions within an ecosystem.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: A niche includes how a species uses resources and responds to biotic and abiotic conditions.
  3. Check scale and evidence: The correct answer is A species' role, resource use, and interactions within an ecosystem.

A niche includes how a species uses resources and responds to biotic and abiotic conditions.

9. QuestionMultiple choice

What does carrying capacity mean?

Please select an answer first.

Correct answer: A

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

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Carrying capacity depends on resource availability, environmental conditions, and interactions that affect survival and reproduction.
  3. Check scale and evidence: The correct answer is The population size an environment can support over time.

Carrying capacity depends on resource availability, environmental conditions, and interactions that affect survival and reproduction.

10. QuestionMultiple choice

Why can an invasive species reduce native biodiversity?

Please select an answer first.

Correct answer: B

The correct answer is It may compete for resources, introduce disease, or disrupt existing interactions.

  1. Identify the environmental system: Determine the population, ecosystem, resource, pollutant, cycle, or climate process described in the question.
  2. Apply the environmental principle: Invasive species can lack natural controls and alter competition, predation, disease, and habitat structure.
  3. Check scale and evidence: The correct answer is It may compete for resources, introduce disease, or disrupt existing interactions.

Invasive species can lack natural controls and alter competition, predation, disease, and habitat structure.
