Study Notes
Biodiversity Overview
- Biodiversity encompasses the variety of genes, species, and ecosystems that make up life on Earth.
Genetic Diversity within a Species
- Genetic diversity within a species allows for adaptation to changing environments and increases the likelihood of survival.
- It provides a species with the ability to evolve and respond to new challenges, such as disease and climate change.
Species Roles in Ecosystems
- Different species play unique roles in ecosystems, such as pollinators, decomposers, and predators.
- Each species contributes to the functioning and balance of ecosystems, and their loss can have cascading effects.
Ecosystem Services
- Besides essential services like air and water purification, ecosystems provide:
- Food and nutrient cycling
- Climate regulation
- Soil formation and maintenance
- Coastal protection and recreation opportunities
Importance of Biodiversity
- Biodiversity is crucial for the health and resilience of our planet because it:
- Maintains ecosystem functioning and services
- Supports human well-being and livelihoods
- Provides natural disaster protection and climate change mitigation
- Offers opportunities for new medicines, foods, and other resources
