Ecology/Ecosystems - Wikibooks, open books for an open worldAn ecosystem can be described simply as the collection of all living and non-living components in a particular area. The living components of the environment are known as biotic factors. Biotic factors include plants, animals, and micro-organisms. The non-living components of the environment are known as abiotic factors. Abiotic factors include things such as rocks,water,soil,light,rocks etc The idea of the ecosystem relates to the idea that all organisms in the environment are engaged in relationships with every other aspect like resources and other organisms in that environment. For example, a household or a university could be described as an ecosystem, and a city or a state could be described as a larger ecosystem.

NCBI Bookshelf. Opportunities in Biology. As we enter the last decade of the twentieth century, we face greater environmental problems than humans have ever faced. We are confronted with changes in the distributions and exchanges of elements on broad scales, with the alarming loss of biotic and habitat diversity, with the consequences of species invasions, with toxification and contamination of our aquifers and other systems, with the disposal of hazardous wastes, and with the collapse of resource systems. As never before, we need to improve our understanding of basic ecological principles: of the factors governing the interrelations between organisms and their environments, of the mechanisms governing the structure and functioning of ecosystems, and of the patterns of response of ecosystems to stress. Our ability to deal with environmental problems will depend on learning to manage systems, which must ultimately be based on advances in basic science. Ecology occupies a unique position in biology because it relates directly to issues and concepts that are widely viewed as being in the public domain.
An ecosystem is the largest organizational unit of life on Earth, defined by a physical environment and the organisms that make their living there. The revised FOSS Populations and Ecosystems course draws from the original course's rich, active-learning investigations to help students learn that every organism has a role to play in its ecosystem, and has structures and behaviors that allow it to survive. This course provides the first steps of ecological understanding for students, with the hope that their future steps will be considered and measured, with the interests of all life being served. Instructionally, the course has been enhanced by the addition of embedded notebooking techniques, recommended homework assignments, and greater support for in-class readings and multimedia activities.
