Biodiversity and Index of Diversity

The video tutorial by Miss A covers biodiversity, focusing on species diversity, genetic diversity, and ecosystem diversity. It explains the importance of biodiversity, the impact of human activities like farming, and how to measure biodiversity using the index of diversity. The tutorial also discusses compromises in farming practices to conserve biodiversity.

What are the three measures of biodiversity discussed in the video?

• Species diversity, habitat diversity, climate diversity

• Habitat diversity, species diversity, climate diversity

• Species diversity, genetic diversity, ecosystem diversity

• Genetic diversity, climate diversity, ecosystem diversity

Why is biodiversity important according to the video?

• It increases the number of predators in an area

• It reduces the need for human intervention

• It ensures the survival of only one species

• It helps in measuring changes in ecosystems

Which human activity is highlighted as reducing biodiversity?

• Urban development

• Deforestation

• Farming practices

• Industrial pollution

What is the significance of a low biodiversity in harsh environments like deserts?

• It shows a high level of species adaptation

• It indicates a healthy ecosystem

• It is expected due to harsh abiotic factors

• It suggests human interference

What is monoculture in the context of farming practices?

• Using natural fertilizers

• Rotating crops every year

• Growing only one plant species in an entire field

• Growing multiple plant species in one field

What is a potential compromise mentioned for maintaining biodiversity in farming?

• Removing all hedgerows

• Using only monoculture

• Implementing crop rotations

• Avoiding any form of breeding

What is the main difference between species richness and index of diversity?

• Species richness considers only the number of species

• Index of diversity considers only the number of species

• Species richness considers the number of individuals within each species

• Index of diversity considers the number of individuals within each species

What does the capital 'N' represent in the index of diversity formula?

• Total number of species

• Total number of individuals of one species

• Total number of organisms of all species

• Total number of habitats

What is the typical range for the index of diversity values?

• Between 1 and 5

• Between 1 and 10

• Between 5 and 10

• Between 3 and 6

Why is it important to practice calculating the index of diversity?

• It is required for all biology courses

• It is used to predict weather patterns

• It helps in identifying new species

• It is a common question in exams
