How does the way that matter flows through an ecosystem differ from the way that energy flows? Angel from Hell?


Matter and energy both flow to ecosystems in a way that is recycled and reused.

Systems ecology is an interdisciplinary field of ecology, taking a holistic approach to the study of ecological systems, especially ecosystems.]citation needed[ Systems ecology can be seen as an application of general systems theory to ecology. Central to the systems ecology approach is the idea that an ecosystem is a complex system exhibiting emergent properties. Systems ecology focuses on interactions and transactions within and between biological and ecological systems, and is especially concerned with the way the functioning of ecosystems can be influenced by human interventions. It uses and extends concepts from thermodynamics and develops other macroscopic descriptions of complex systems.

Systems ecology seeks a holistic view of the interactions and transactions within and between biological and ecological systems. Systems ecologists realise that the function of any ecosystem can be influenced by human economics in fundamental ways. They have therefore taken an additional transdisciplinary step by including economics in the consideration of ecological-economic systems. In the words of R.L. Kitching:

Biology Symbiosis Environment Ecology Science Ecosystem Superorganisms Energy

The term anthroposystem is used to describe the anthropological analogue to the ecosystem. In other words, the anthroposystem model serves to compare the flow of materials through human systems to those in naturally occurring systems. As defined by Santos, an anthroposystem is "the orderly combination or arrangement of physical and biological environments for the purpose of maintaining human civilization...built by man to sustain his kind." The anthroposystem is intimately linked to economic and ecological systems as well.

Both the anthroposystem and ecosystem can be divided into three groups: producers, consumers, and recyclers. In the ecosystem, the producers or autotrophs consist of plants and some bacteria capable of producing their own food via photosynthesis or chemical synthesis, the consumers consist of animals that obtain energy from grazing and/or by feeding on other animals and the recyclers consist of decomposers such as fungi and bacteria.

Ecosystem ecology is the integrated study of biotic and abiotic components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals, bedrock, soil, plants, and animals.

Ecosystem ecology examines physical and biological structures and examines how these ecosystem characteristics interact with each other. Ultimately, this helps us understand how to maintain high quality water and economically viable commodity production. A major focus of ecosystem ecology is on functional processes, ecological mechanisms that maintain the structure and services produced by ecosystems. These include primary productivity (production of biomass), decomposition, and trophic interactions.

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.

Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
