10 Examples of a Natural Ecosystem

Natural ecosystems are often as unique as the creatures that inhabit them. Here are ten examples of land and water ecosystems.


An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes.

Permaculture Design - Thinking Like an Ecosystem

Permaculture is often difficult to define as it is not so much A Thing, as a way of thinking. It is in essence an ecological design process which can be applied to all areas of human life. The word is a combination of the words 'permanent agriculture' created by the founders of the movement who aimed to find sustainable alternatives conventional agriculture practices.
