11.1 Biodiversity

Question 1

What is biodiversity?

Answer 1

variety of living organisms

present in an area

Question 2

What are the different components of biodiversity/what factors are taken into account?

Answer 2

• HABITAT BIODIVERSITY
  
  • Number of different habitats in a given area
• SPECIES BIODIVERSITY
  
  • Species Richness - number of different species
  • Species Evenness - relative abundance of species
• GENETIC BIODIVERSITY
  
  • Variety of alleles making up a species

Question 3

What is habitat biodiversity?

Answer 3

number of different habitats

in a given area

Question 4

What are the components of species biodiversity?

Answer 4

Species evenness

Species richness

Question 5

What is species richness?

Answer 5

number of different types of species

Question 6

What is species evenness?

Answer 6

relative populations of different species

Question 7

What is genetic biodiversity?

Answer 7

variety of alleles within a species

Question 8

What is an advantage of having a high genetic biodiversity?

Answer 8

increased intraspecific variation,

so change in environment is unlikely to affect every individual,

so less likely for species to become extinct

Question 9

What is an advantage of high biodiversity?

Answer 9

ecosystem more stable
