Practice This ConceptMain explanation
Teacher explanation
Different organisms do not obtain food in the same way. Green plants make food by photosynthesis, while animals and fungi depend on other sources. Nutrition is not only eating; it also includes digestion, absorption, transport, and use of food by cells.
Example
A green plant making glucose in leaves and a human digesting rice are both examples of nutrition.
Simple analogy
Nutrition is not just eating; it is food used for life.
Common confusion
Students often think nutrition means only eating food or only digestion.
Exam tip
