Dangers to food chains (non-statutory Climate Change & Sustainability)

More about food chains

Unit Summary

This unit involves constructing and interpreting food chains and identifying producers, predators, and prey. It focuses on asking questions, gathering and presenting data, recording findings with diagrams and charts, and using scientific evidence to answer questions and support findings.

Lesson Summary

You will learn to describe the impact on food chains when humans cause habitats to change.

Key Notes

  • Some plants and animals in different food chains are in danger.
  • Humans can cause the habitats of plants and animals to change by cutting down trees or hunting.
  • When habitats change, the number of plants and animals living there may also change.

Vocabulary To Learn

  • danger: Danger is the possibility of death or harm to something.
  • extinct: Animals or plants that have died out completely are extinct.
  • habitat: The place where a plant or animal lives is called its habitat.
  • impact: The impact of something is the effect it has.

Common Mistakes To Avoid

  • Pupils may think that different parts of a food chain are independent of each other and are not impacted by changes elsewhere in the food chain.

3 Quick Questions (With Answers)

1. Explain the scientific idea in this lesson using two key points.

Some plants and animals in different food chains are in danger. Humans can cause the habitats of plants and animals to change by cutting down trees or hunting.

2. Define this scientific word and use it in context. 'danger'

Danger is the possibility of death or harm to something. Include the word in a full scientific explanation, not as a single label.

3. Correct this common scientific misunderstanding.

Mistake: Pupils may think that different parts of a food chain are independent of each other and are not impacted by changes elsewhere in the food chain. Correction: Clear explanation of how each part of a food chain is linked to other parts of the chain and how even small changes can have a big impact throughout a food chain.
