Biology 310: Ecosystem vs. BiosphereAn ecosystem defines a community of living things and their symbiotic relationships. Ecosystem goes further, to incorporate the relationship of also nonliving thing available in that community. Therefore, ecosystem can easily be, defined as relationships and interactions of both living and nonliving things in a community (Detlev 2010). Biosphere, on the other, hand, refers to the outermost part of the earth plant that carries all the relationships of living things; ranging from living, nonliving, air, rocks, oxygen, and an entire ecosystem. Therefore, biosphere refers to an amalgamation of ecosystems into one big ecosystem that carries living organism, nonliving organism, and their relationships for coexistence. This paper examines the similarities and differences between Ecosystem and Biosphere. Ecosystem and biosphere are similar with each other in the sense that they both housing living organisms in their environments. Both ecosystem and biosphere create symbiotic relationships between living and non-living organisms in their ecosystem. Finally, ecosystem and biosphere encourage the evolution of life through the different relationships and interactions among organisms in their environment (Neil & Williamson 2006). The core differences between ecosystem and biosphere focuses on, biosphere represents the global ecosystem while ecosystem represents organisms in a community
