    Study Notes

    Biology: The Science of Life

    • Biology is the study of life, and it encompasses the diversity of life on Earth, including plants, microbes, animals, and people.

    Characteristics of Living Organisms

    • Living organisms require energy, which is primarily sourced from the sun through photosynthesis.
    • Photosynthesis is the process by which some organisms capture solar energy and transform it into chemical energy.
    • Other organisms, called consumers, cannot use photosynthesis for energy and instead consume and metabolize nutrient molecules.
    • In an ecosystem, chemical cycling and energy flow begin when plants produce their own food using solar energy and inorganic nutrients.
    • Chemicals and energy are passed from one population to another in a food chain as organisms feed on each other.
    • With the death and decomposition of organisms, chemicals are returned to plants, and energy eventually dissipates and returns to the atmosphere as heat.

    Reproduction

    • Organisms reproduce either sexually (producing genetically different progeny) or asexually (producing genetically identical progeny).

    Response to Environmental Changes

    • Irritability is the ability of an organism to recognize and respond to changes in its surroundings.
    • Adaptation is a phenotypic response to an environmental change, such as structural adaptations in plants that have adapted to life in dry, hot deserts.
    • Evolution is the genetic change in a population over time, producing a new population.

    Adaptation and Homeostasis

    • Living organisms adapt to their environment by making modifications to suit their way of life.
    • Examples of adaptations include hawks catching fish or rabbits, and humans living at extreme elevations exhibiting adaptations that reduce hemoglobin in the blood.
    • Homeostasis is the ability of an organism to maintain its internal environment stably despite changes in the external environment.

    Levels of Biological Organization

    • The cell is the basic unit of life, and all living things are made up of cells.
    • Unicellular organisms are made up of one cell, while multicellular organisms are made up of more than one cell.

    Domains and Kingdoms of Life

    • The most inclusive and general classification is the Domain.
    • The three domains of life are Archaea, Bacteria, and Eukarya.
    • Each domain is further divided into different kingdoms, such as Protists, Plants, Animals, and Fungi.
    • Examples of organisms in each domain and kingdom include Methanosarcina mazei, Escherichia coli, and Homo sapiens.
