Ecosystems

Key topics in Ecosystems include Mind map showing the two main categories of ecosystem components—biotic (living) and abiotic (non-living)—with examples of each., Flowchart showing how green plants capture sunlight and convert it into food energy through photosynthesis, forming the base of the food chain., Flowchart showing how primary consumers (herbivores) eat plants and form the first step of the food chain.. These are the concepts ICSE Class 8 examiners draw on most — study them first, then practise related questions.

Understand the core concepts first, then work through the 44 practice questions available for this chapter. Revise formulas and definitions regularly, and use flashcards for quick recall before the exam.
