This chapter explores some of the ecological topics not already discussed elsewhere in the text.
Regional issues, including acid deposition, water contamination, wetlands, and hazardous waste, are discussed first. Then global matters are introduced with a discussion of populations, communities, and ecosystems. This is followed by a brief look at producers, primary and secondary consumers, decomposers, and food chains. Then energy flow through an ecosystem is considered, and the nitrogen, carbon, and water cycles are explored. Discussions of succession and fire ecology follow. Human disruption of ecosystems, including ozone depletion, global warming, and loss of biodiversity, conclude the chapter.

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
