    Study Notes

    Biodiversity and Ecosystems

    • Biodiversity refers to the variety of different species of plants, animals, and microorganisms that live in an ecosystem or on Earth as a whole.

    Habitats and Species

    • A habitat is the natural environment in which an organism or species normally lives or occurs.
    • A species is independent if it can survive and reproduce on its own without relying on another species.

    Vertebrates and Invertebrates

    • The main difference between vertebrates and invertebrates is the presence or absence of a backbone.
    • Vertebrates have a backbone, while invertebrates do not.

    Interdependence and Food Chains

    • Interdependence refers to the way different species in an ecosystem rely on each other for survival.
    • If one type of animal disappears, it may have a ripple effect throughout the ecosystem, potentially affecting other species that rely on it.
    • Disrupting the food chain, a series of organisms that eat other organisms, can have consequences for the entire ecosystem.

    Species and Their Environments

    • If you match a bird to its habitat, it would most likely live in an environment that provides the necessary resources for its survival, such as food, water, and shelter.

    Ecological Relationships

    • The term that best describes the relationship between plants and animals in an ecosystem is interdependence.

    Key Characteristics of Biodiversity

    • The characteristic that best defines biodiversity is the variety of different species present in an ecosystem or on Earth.
