    Study Notes

    Endangered Species and Extinction

    • Many species face extinction risk.
    • Protecting habitats and preventing deforestation are crucial to preventing extinction.

    Animal Classification

    • Herbivores eat plants; carnivores eat meat; omnivores eat both.
    • Animals have varying body coverings (scales, fur).
    • Mammals are viviparous (give birth to live young); reptiles and fish are oviparous (lay eggs).

    Environmental Challenges

    • Pollution (e.g., pesticides) and climate change (e.g., greenhouse effect) threaten ecosystems.
    • Greenhouse gases trap heat, causing global warming and extreme weather events.
    • Soil, air, and water contamination result from excessive pesticide use.

    Energy Sources and Conservation

    • Fossil fuels (oil, natural gas, coal) are non-renewable sources and pollute.
    • Renewable energy (solar, hydropower) are safer alternatives to fossil fuels.
    • Conservation is essential to protect ecosystems and wildlife.
