Biodiversity

Multiple Choice

Which of the following best describes genetic biodiversity?

• The variety of species within a habitat or region

• The variation of DNA and genes within a species or population

• The variation in the network of species present in a location

• The number of individuals in a population

Multiple Choice

What does a higher biodiversity index indicate about an environment?

• Lower diversity of species

• Greater diversity of species

• Fewer individuals in the area

• More invasive species

Multiple Choice

What is the purpose of calculating biodiversity index?

• To measure and quantify the diversity of species in a given area or ecosystem.

• To calculate the total biomass of a given area or ecosystem.

• To identify the dominant species in a given area or ecosystem.

• To determine the average temperature in a given area or ecosystem.

Multiple Choice

What does a lower biodiversity index value indicate?

• A higher level of biodiversity

• No impact on biodiversity

• An average level of biodiversity

• A lower level of biodiversity

Multiple Choice

What is the range of biodiversity index values?

• -1 to 1

• 0 to 1

• 1 to 10

• 0 to 100

Multiple Choice

Why is it important to interpret biodiversity index values?

• To understand the health and condition of ecosystems and make informed decisions for conservation and management.

• To determine the number of species in an ecosystem.

• To identify the dominant species in an ecosystem.

• To measure the temperature and weather patterns in an ecosystem.

Multiple Choice

Why is "A" less biodiverse than "B"?

• Image "A" is more biodiverse.

• Image "A" has many corn plants and this makes it have high "rich" biodiversity.

• Image "A" has a lot more plants than image "B"

• Even though "A" has a lot of corn plants they are all the same species and makes this a low "poor" biodiverse area.

Multiple Choice

An ecosystem has 150 organisms of 15 different species. What is the biodiversity index of this ecosystem?

• 165

• 10

• 0.15

• 0.1

Multiple Choice

Using the formula and data, calculate the biodiversity index 

• 0.2

• 0.27

• 0.19

• 0.21

Multiple Choice

In a forest ecosystem, there are 200 trees of 20 different species. What is the biodiversity index if calculated using the formula: number of species/total number of organisms?

• 0.1

• 0.2

• 10

• 20

Multiple Choice

What does a biodiversity index of 1 indicate about an ecosystem?

• High biodiversity

• Low biodiversity

• No biodiversity

• Moderate biodiversity

Multiple Choice

Why is a high biodiversity index important for an ecosystem?

• It indicates a stable and resilient ecosystem

• It shows the ecosystem is under threat

• It means the ecosystem has few species

• It suggests the ecosystem is artificial

Multiple Select

Which of the following are methods or indicators used to measure biodiversity in an area?

• Biodiversity index

• Line transects

• Counting only invasive species

• Observing only one species

Multiple Choice

Which statement about invasive species is true?

• lots of animals eat them

• they get killed off quickly

• they reproduce quickly

Multiple Choice

What is something that is common to most invasive species?

• they don't live long

• they can't have babies in the new area

• they can't eat anything in the new area

• they don't have many predators in their new area

Multiple Choice

Which ecosystem is more diverse?

• Ecosystem A

• Ecosystem B

• They're have the same biodiversity

• Not enough information
