3.1-An introduction to biodiversity Part -2

Biodiversity refers to:

   

• The number of species in an area

     

• The complexity of an area

     

• The health of an area

   

•   All of the above

Which of the following is NOT a way to measure biodiversity?

•     Species diversity

     

• Habitat diversity

     

• Genetic diversity

   

•   Ecological diversity

Richness in biodiversity refers to:

 

•   The number of species in an area

     

• The relative abundance of each species

     

• The variability of a community

     

• The complexity of an ecosystem

What does the Simpson's index measure?

   

• Species richness

     

• Genetic diversity

     

• Habitat diversity

• Species evenness

Genetic diversity refers to:

  

•  The number of genes within a species

     

• The number of species within an area

    

•  The variability of ecological niches

    

•  The complexity of an ecosystem

Which type of diversity is most likely to lead to an increase in the other two types?

   

• Species diversity

     

• Habitat diversity

     

• Genetic diversity

     

• Ecological diversity

Conservation aims to:

   

• Increase human-made disturbances

     

• Protect habitats and ecosystems

     

• Exploit natural resources unsustainably

     

• Accelerate the rate of extinction

How can the effects of human activities on ecosystems be assessed?

   

• By comparing species richness in different areas

     

• By using diversity indices like Simpson's index

     

• By measuring the physical characteristics of species

     

• By studying the variability of ecological niches

 Hotspots are areas that:

 

•    Have low species richness

     

• Are heavily disturbed by human activities

     

• Contain large numbers of endemic species

     

• Exhibit low genetic diversity

Which of the following is NOT a factor that affects the assessment of species richness?

    

• Sampling technique

      

• Sample size

      

• Relative abundance of species

      

• Habitat type
