The biosphere includes the narrow layer of Earth inhabited by living things. Elements of the biosphere interact with the lithosphere (land), hydrosphere (water), and atmosphere (air) to result in the conditions that we find on earth. The biosphere includes all of the different ecosystems in which life is found from the tundra of the Arctic to the African savannah. Many of the macroscopic interactions, such as predation and competition for limited resources are well understood. Other interactions such as the spread of disease, the impact of invasive species, and human influenced depletion of natural resources are less understood and remain the topics of active investigation.Conceptual StrandAll life is interdependent and interacts with the environment.Guiding QuestionHow do living things interact with one another and with the non-living elements of their environment?
