    Study Notes

    Levels of Biological Organization

    • A group of cells are called tissues
    • A group of tissues are called organs
    • A group of organs are called organ systems

    Plant Organs

    • Plant organs include roots, stems, and leaves

    Organ Systems

    • An organ system is a group of organs with related functions that work together to perform body functions

    Ecology

    • Organisms of the same species that live in the same area make up a population
    • All populations that live in the same area make up a community
    • A community includes populations of different species, such as fish, coral, and other organisms

    Ecosystem

    • An ecosystem consists of all living organisms (biotic factors) and nonliving environment (abiotic factors) in a specific area
    • The nonliving environment includes water, sunlight, soil, and other physical factors

    Biodiversity

    • Life on Earth is very diverse
