Life Science
1. Investigate the great variety of body plans and internal structures found in multicellular organisms.
2. Investigate how organisms or populations may interact with one another through symbiotic relationships and how some speicies have become so adapted to each other that neither could survive without the other (e.g., predator–prey, parasitism, mutualistism, commensalism).
3. Explain how the number of organisms an ecosystem can support depends on adequate biotic (living) resources (e.g., plants, animals) and abiotic (nonliving) resources (e.g., light, water, soil).
4. Investigate how overpopulation impacts an ecosystem.
5. Explain that some environmental changes occur slowly while others occur rapidly (e.g., forest and pond succession, fires and decomposition).
6. Summarize the ways that natural occurrences and human activity affect the transfer of energy in Earth’s ecosystems (e.g., fire, hurricanes, roads, oil spills).
7. Explain that photosynthetic cells convert solar energy into chemical energy that is used to carry on life functions or is transferred to consumers and used to carry on their life functions.
8. Investigate the great diversity among organisms.
