Study Notes

Endangered Species

  • Many species face extinction.
  • Habitat loss (e.g., deforestation) threatens species.
  • Conservation efforts are vital for survival.

Animal Diversity

  • Herbivores, carnivores, and omnivores represent different diets.
  • Body coverings vary: scales, fur.
  • Reproduction methods differ (oviparous, viviparous).

Environmental Challenges

  • Pollution (e.g., pesticides) harms various environments.
  • Climate change leads to extreme weather events (floods, droughts).
  • Greenhouse effect, caused by gases, traps heat.

Energy and Conservation

  • Fossil fuels (oil, gas, coal) pollute the environment.
  • Renewable energy (solar, hydro) are safer options.
  • Conservation is essential for a sustainable future.
