Answer:
The quality of life is dependent on the quality of the environment in which the organism lives in. An ecosystem is made up of biotic and abiotic components which are interrelated.
For example, the quality of the water resources of an ecosystem would affect the quality of the humans that live in there. Although an ecosystem could have a lot of water, this does not mean that the water is usable as a source for hydration, which is needed by humans. If the quality of the water is bad, like it is polluted or contaminated, this would not make it a good source for drinking water, which affects the quality of life.
Another would be the availablity of clean and breathable air. Trees are our sources for oxygen and they filter out carbon dioxide in the air naturally as components of their own food making process. The decrease or lack of trees would mean that there would be less production of oxygen for humans to take in.
Earthworms maintain homeostasis by having a dual circulatory system, which contains the closed circulatory system and the coelomic fluid for respiratory gases, food and waste.
