1. Key Ideas

All living things need energy and nutrients — but not all of them get it the same way. Understanding the fundamental difference between organisms that make their own food and those that consume others is the conceptual anchor for everything in Inquiry Question 2.

Define autotroph and heterotroph with examples
Compare the nutrient and gas requirements of autotrophs and heterotrophs

2. Success Criteria

By the end, you should be able to:

Define autotroph and heterotroph with examples
State the inputs and outputs of photosynthesis
State the inputs and outputs of cellular respiration

3. Analyse why this idea matters for understanding Autotrophs vs Heterotrophs — Nutrient and Gas Requirements: "State the inputs and outputs of cellular respiration".

Band 54 marks

6. Extend: Apply the Idea

Band 5/65 marks

A student gives a memorised answer about Autotrophs vs Heterotrophs — Nutrient and Gas Requirements but does not use evidence or reasoning.

Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
