Emphasis is given to the relationships of plant individuals and populations to their environments and to their roles in ecosystems. The text is directed to the reader who knows little or nothing about ecology. He should finsish his reading with a better appreciation of the intricacy and delicacy of the relationships between organisms and their environments, and he should also realize the urgency of understanding the functioning of ecosystems, those complex natural machines upon which we all depend.
