ecosystem to which it has been introduced.
3. Identify the biome in which we live and summarize its abiotic and biotic
characteristics. Do these reflect what you see in your neighborhood? Explain.
4. List the following from least to most specific: population, organism,
ecosystem, community

same based on age structure diagrams.
5. I can describe the problems associated with estimating Earth’s carrying
capacity for the human species, and summarize the current trends in human
population growth.
