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?
Elements within this Standard
Course Level Expectation
Investigate how the dynamic equilibrium of an ecological community is associated with interactions among its organisms.
Analyze and interpret population data, graphs, or diagrams.
Predict how global climate change, human activity, geologic events, and the introduction of non-native species impact an ecosystem.
Describe the sequence of events associated with biological succession.
Check For Understanding
Analyze human population distribution graphs to predict the impact on global resources, society, and the economy.
Construct and maintain a model of an ecosystem.
Monitor and evaluate changes in a yeast population.
Investigate an outdoor habitat to identify the abiotic and biotic factors, plant and animal populations, producers, consumers, and decomposers.
Conduct research on how human influences have changed an ecosystem and communicate findings through written or oral presentations.
Describe a sequence of events that illustrates biological succession.
State Performance Indicator

Determine how the carrying capacity of an ecosystem is affected by interactions among organisms.
Predict how various types of human activities affect the environment.
Make inferences about how a specific environmental change can affect the amount of biodiversity.
Predict how a specific environmental change may lead to the extinction of a particular species.
Analyze factors responsible for the changes associated with biological succession.
