IGCSE Bio Topic 19 – Organisms and their Environment

For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. A powerpoint can be downloaded from the same site here. The s-cool revision site lets you revise the topic, summarizes the topic & tests you on it. Skoool gives you a lesson, including progress questions, for each Biology topic but you’ll need sound on for it. And both these sites –  GCSE Bitesize & GCSE Bitesize – have revision pages (that take you through the topic), a test and an activity. 

Topic 19 revision notes in downloadable word format; to be completed.
