Biodiversity, Ecosystems, and
Resilience
Learning Objectives
▪ Explain the types of biodiversity.
▪ Identify the benefits of biodiversity.
▪ Identify some important ecosystem benefits.
Types of Biodiversity
Biodiversity is the total of all genetically based variation in all
organisms in the biosphere.
Types of biodiversity:
• ecosystem diversity
• species diversity
• genetic diversity
Biodiversity Benefits
• Contributes to medicine and agriculture
• Enables organisms and ecosystems to adapt to
environmental change
Biodiversity, Medicine, and Agriculture
Many medicines were first
discovered in wild species.
Genetic diversity is
important in agriculture.
Wild plants may carry
useful genes.
Biodiversity and Ecosystem Resilience
• Resilience describes a natural or human system’s ability
to recover after a disturbance.
• The more biodiversity an ecosystem has, the more
resilient it is likely to be.
Ecosystem Services and Biodiversity
Ecosystem services are the benefits provided by
ecosystems to humans.
