This book is part of the Cambridge Modular Sciences series for A and AS
level. It aims to develop an understanding of: ecology and the complex
interactions occurring in an ecosystem, the importance of practical
investigation in the ecology of plant and animal communities, the fact
that conservation can occur at local, national and international levels,
different interest groups and their objectives when setting up a
conservation programme. To help the student, learning objectives are
listed at the start of each chapter and self-assessment questions are
scattered throughout the text. Answers to these are provided at the back
of the book. Each chapter concludes with a summary and longer questions.
