Study Notes
Biodiversity Overview
- Total variety of all life on Earth is termed biodiversity.
- Biodiversity encompasses different species, ecosystems, and genetic variations.
Importance of Biodiversity
- Biodiversity is crucial for ecosystem stability, resilience, and productivity.
- It provides essential services such as pollination, nutrient cycling, and water purification.
Role of Forests
- Towering forests cover one-third of the Earth's land surface, acting as crucial carbon sinks.
- They play a vital role in regulating the climate, maintaining water cycles, and supporting diverse life forms.
Role of Coral Reefs and Mangrove Swamps
- Coral reefs support marine biodiversity and protect coastal areas from erosion.
- Mangrove swamps serve as vital nurseries for many fish species and help in coastal protection.
Agriculture and Food Supply
- Millions of ? (specific species not detailed) are needed to sustain food production and agricultural diversity.
- Genetic diversity in crops ensures resilience against pests, diseases, and changing climate conditions.
