Complete answer:An ecosystem is a geographical region where plants, animals, and other species work together to form a bubble of life, as is the atmosphere, and landscape. Ecosystems include biotic or living elements, as well as abiotic or non-living components. Plants, livestock, and other species are part of biotic factors.
The German zoologist Ernst Haeckel, who applied the term "ecology" to the relationship between the organic and inorganic world of the species, coined the word "ecology" in 1866. The words derived from the Greek "Oikos' meaning household, home or a livelihood, and "logo" means learning the way organisms react to their environments. So, the study of organisms at home is basically ecological. Ecology focuses on the study of energy flow and environmental materials. The analysis and work of nature. It also deals with the exchange of different products, including biogeochemical cycles, between the biotic and abiotic components of the ecosystem. Ecological thinking emerges from existing philosophical trends in ethics and politics in particular
Greek word Oikos, meaning home, as an ecosystem is kind of a house, is the reference name for the word 'Ecosystem.'
Hence, the correct answer is option C-house.
