Study Notes

Biodiversity is the variety of species on Earth
It includes species richness, abundance, genetic and ecological variability
Simpson's index of diversity is a measure of an ecosystem's biodiversity
A low index of diversity suggests few successful species dominating or a hostile environment
A high index of diversity suggests a more stable ecosystem with more successful species and ecological niches
Humans have influenced the environment more than any other species
Habitat loss, overexploitation, and introduction of exotic species are some of the threats to biodiversity
Genetic variability is important for biodiversity as it helps populations adapt to environmental changes
Rhododendron bushes prevent other plants from growing and dominate the area, leading to low index of diversity

Description

This quiz will test your knowledge of biodiversity, the variety of species on Earth. Learn about the different factors that contribute to biodiversity, including species richness, abundance, genetic and ecological variability. Discover the Simpson's index of diversity, a measure of an ecosystem's biodiversity, and what a low or high index suggests about the ecosystem. Explore the threats to biodiversity, such as habitat loss, overexploitation, and introduction of exotic species, and why genetic variability is important for biodiversity.
