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.

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.
