Answer:
ecosystem
Step-by-step explanation:
An ecosystem includes all of the living things (plants, animals and organisms) in a given area, interacting with each other, and also with their non-living environments (weather, earth, sun, soil, climate, atmosphere). The living and nonliving components of the ecosystem are linked together through nutrient cycles and energy flows. Ecosystems are of any size, but usually they are in particular places.
In an ecosystem, plants depend on the soil for nutrients. These nutrients are cycled in nature by the various biogeochemical cycles within the ecosystem. The ecosystem is a self sustaining unit in terms of materials and energy flow.
