This series describes the basic needs of most plants and animals. Each topic is introduced by looking at human needs, so the reader can compare and contrast their own needs with those of plants and animals. The titles use a range of familiar examples to show the variety of ways living things get the basic necessities of life and also look at how some living things have adapted to survive without, or with only, limited resources. Other features include spreads with questions and answers and 'Can you guess?' quizzes relating to book's content.
