    Study Notes

    Scientific Inquiry

    • Observation is essential for forming a hypothesis in scientific inquiry
    • A hypothesis is a testable prediction that guides further investigation

    Characteristics of Living Organisms

    • One characteristic feature of living organisms is the ability to maintain homeostasis
    • Homeostasis is the regulation of internal environment despite external changes

    Ecosystems

    • Producers, such as plants and algae, primarily perform the function of photosynthesis in ecosystems
    • Photosynthesis involves the conversion of light energy into chemical energy

    Scientific Experiments

    • A primary component of a scientific experiment is a controlled variable
    • A controlled variable is a factor that is kept constant to ensure accurate results

    Energy Transfer

    • Energy transfer primarily involves the transfer of energy through food chains in ecosystems
    • Energy is transferred from one trophic level to the next through consumption of organisms
