The Eyewitness Science series follows the story of science, tracing the major discoveries through the eyes of the great scientists. The text is simple and straightforward, and each spread contains detailed artwork and photographs. The series combines landmark experiments in the history of science with the human element - the great men and women of science. Special features include: demonstrations which re-create experiments and expand important principles; artworks which explain how and why things work; specially built 3-D models which aim to make clear even the most complex concepts; and words and pictures which work together to explain scientific principles clearly and concisely. Ecology covers such topics as nature's producers; decomposers; carbon cycles; minerals and soils; and ecological competition.
