7 Questions
What is biodiversity?
The variety of species on Earth
What does Simpson's index of diversity measure?
The variety of species on Earth
What does a low index of diversity suggest?
A hostile environment
What are some threats to biodiversity?
Habitat loss, overexploitation, and introduction of exotic species
Why is genetic variability important for biodiversity?
It helps populations adapt to environmental changes
What effect do Rhododendron bushes have on biodiversity?
They prevent other plants from growing and dominate the area, leading to low index of diversity
What is an example of high biodiversity?
A tropical rainforest ecosystem
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
- Tropical rainforests are an example of high biodiversity.
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. Test your understanding of these
