What is considered high biodiversity?
High biodiversity, with many species present, is good. It usually means that an ecosystem is healthy and relatively undisturbed by humans. Low biodiversity is characteristic of an unhealthy or degraded environment. A mown lawn in a city park is an example of an ecosystem with low biodiversity.
Where is biodiversity the greatest?
The area on Earth considered to have the greatest biodiversity is the Tropical Andes region covering 1,258,000 km² (485,716 miles²) and running through Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and a small area of northern Argentina.
Where are the highest levels of biodiversity on our planet?
Tropical ecosystems support higher levels of biodiversity than temperate or boreal ecosystems. Tropical rainforests and coral reefs are the most diverse ecosystems on the planet. Between 50 and 90 percent of Earth’s plant and animal species are found in tropical regions.
What are characteristics of ecosystems with high biodiversity?
Ecosystems that have high levels of biodiversity have a large number of species, complex food webs, a variety of ecological niches, increased genetic diversity, and abundant resources.
What happens when there is high biodiversity?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
Why wetlands have a high biodiversity?
Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.
Why is high biodiversity advantageous over low biodiversity?
The higher the biodiversity of an ecosystem, the more sustainable it is. Conversely, lower biodiversity equals less sustainability. The biodiversity of an ecosystem contributes to the sustainability of that ecosystem. Higher/more biodiversity = more sustainable.
