    1. Unit 2 Chapter 5 Biological Diversity and Conservation

    2. Biodiversity The variety of species in a specific area Ecosystems are stable if their biodiversity is maintained

    3. Loss of biodiversity Extinction The disappearance of a species when the last of its species dies

    4. Loss of biodiversity Endangered species When numbers become so low that extinction is possible

    5. Threats to Biodiversity Habitat destruction Loss of a habitat that cannot be reestablished easily, causing certain organisms to become vulnerable to extinction

    6. Threats to Biodiversity Ozone layer Absorbs some of the ultraviolet waves, reducing the ultraviolet radiation reaching Earths surface

    7. Threats to Biodiversity Acid Rain Any precipitation with low pH, linked to the destruction of forests & lakes

    8. Threats to Biodiversity Pollution Degradation of water, land or air environments, due to use of pesticides, algal blooms, etc

    9. Conservation Biology The study and implementation of methods to protect biodiversity Preserving habitats Ex: creation of parks & preserves
