Explanation:
The ecosystem is the basic unit for supporting life, but an ecosystem goes beyond organisms living in one place. Life depends on the recycling of resources between organisms and the environment in which they live, between organic and inorganic forms. Ecosystem ecology studies these transformations and integrates into both terrestrial and aquatic ecosystems, attracting fields as diverse as atmospheric chemistry, hydrology, soil science, physiology, and ecology.
For this reason, The study of nutrient cycling through the environment is an example of subjects that are studied in ecosystem ecology.
