    Study Notes

    Ecosystems

    • An ecosystem is composed of living organisms and their environment.
    • It consists of both biotic (living) and abiotic (non-living) components.

    Biotic Components

    • Examples of biotic components include plants, animals, and microorganisms.

    Importance of Water

    • Water is essential for living things to survive.

    Energy Sources

    • Living things get energy from various sources, including the sun, food, and chemical reactions.

    Symbiosis

    • Mutualism is a type of symbiosis where both organisms benefit from each other.
    • An example of mutualism is the relationship between ants and aphids.
    • Other types of symbiosis include parasitism, commensalism, and predation.

    Adaptation

    • Adaptation is how organisms respond to their environment.
    • It is a key feature of evolution and allows organisms to survive and thrive in different conditions.

    Living Conditions

    • Different types of organisms can live in various conditions, such as extreme temperatures, high salinity, and low oxygen levels.

    True or False Statements

    • True: All living things need water, food, and energy to survive.
    • False: All living things need oxygen to provide the energy they need to survive.
    • True: Symbiosis is a relationship between two different organisms where each partner benefits from the relationship (in the case of mutualism).
    • True: Predation occurs when members of one species eat members of another species.
    • True: Adaptation is how organisms respond to their environment.
