Examples of decomposers/detritivores
Fungi, Bacteria and Invertebrates (worm, insects,…)
an interdisciplinary field that integrates scientific methods and disciplines to understand and address real world environmental challenges
Environmental Science
It is a study that applies scientific and engineering principles to improve and maintain the environment to protect human health, protect nature’s beneficial ecosystems, and improve environmental-related enhancement of the quality of human life
Environmental Engineering
Major Scopes of Environmental Science and Engineering
- Management of Natural Resources
- Conservation of Ecosystem and Biodiversity
- Mitigation and Control of Pollution

Environmental System
It means “variety of life”
Biodiversity
Examples of Environmental System
