What are the services provided by biodiversity?
Many key ecosystem services provided by biodiversity, such as nutrient cycling, carbon sequestration, pest regulation and pollination, sustain agricultural productivity.
How does biodiversity support ecosystem services?
A wide variety of species in an ecosystem provides an ecosystem with greater resistance to disease and pest outbreaks. Plants help protect soil from erosion. An ecosystem with rich biodiversity is more resilient and able to withstand the extinction of an individual species.
Why is biodiversity important who cares?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
What ecosystem services do plants provide?
Plants clean air and filter water, bacteria decompose wastes, bees pollinate flowers, and tree roots hold soil in place to prevent erosion. All these processes work together to make ecosystems clean, sustainable, functional, and resilient to change.
What are the 5 major threats to biodiversity?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
What are the major threats of biodiversity?
Threats to Biodiversity
- Habitat Fragmentation. Ecosystem conversion and ecosystem degradation contribute to habitat fragmentation.
- Exotic Species Introductions. Infestation by alien species, such as the Codling Moth, is also a major threat to BC ecosystems.
- Global Climate Change.
- Corridors and Connectivity.
What are the main components of biodiversity?
Three components of biodiversity are ecosystem, species and genetic diversity. Ecosystems perform functions that are essential to human existence such as oxygen and soil production and water purification.
