Types of Biodiversity
This type of biodiversity refers to the variety of species in a given ecosystem.
What is species diversity?
Bees and butterflies contribute to this critical ecosystem service.
What is pollination?
This activity destroys habitats to make room for farms and cities.
What is habitat destruction?
A protected area where no human activity is allowed is called this.
What is a wilderness area or nature preserve?
The variety of life on Earth is known as this.
What is biodiversity?
The genetic variation within a population represents this type of biodiversity.
What is genetic diversity?
Wetlands help reduce flooding and filter water, an example of this type of service.
What is a regulating service?
The introduction of this type of species can outcompete native species for resources.
What is an invasive species?
The Endangered Species Act was passed in this year.
What is 1973?
This species type, such as amphibians, indicates ecosystem health.
What are indicator species?
The number of different habitats or ecosystems in a region refers to this type.

Forests capturing carbon from the atmosphere is an example of this service.
What is carbon sequestration?
Overhunting or overfishing are examples of this threat.
What is overexploitation?
Zoos that help reintroduce animals into the wild are practicing this conservation strategy.
What is a captive breeding and reintroduction program?
These species play a critical role in maintaining structure of an ecological community, despite often being few in number.

What is ecosystem resilience?
This term describes areas like coral reefs or rainforests with exceptionally high species diversity.
What is a biodiversity hotspot?
The category of ecosystem services that includes soil formation and nutrient cycling.
What is a supporting service?
This process breaks up habitats and isolates species, often caused by roads or development.
What is habitat fragmentation?
The acronym CITES stands for this international agreement protecting species.
What is the Convention on International Trade in Endangered Species of Wild Fauna and Flora?
