Study Notes
Biodiversity
- Biodiversity refers to the variety and variability of life on Earth.
Distribution of Biodiversity
- Biodiversity is usually greater near the equator and decreases towards the poles.
- Tropical forests, which cover less than 10% of Earth's surface, contain about 90% of the world's species.
Levels of Biodiversity
- Biodiversity measures variation at three levels: genetic, species, and ecosystem.
Marine Biodiversity
- Marine biodiversity is usually higher near coral reefs and estuaries.
Factors Affecting Biodiversity
- The primary reason for the uneven distribution of biodiversity on Earth is the variation in climate and temperature.
Future Outlook for Biodiversity
- The future outlook for biodiversity is uncertain and threatened by human activities.
