Biodiversity Within A Community

Question 1

What is biodiversity

Answer 1

The variety of living organisms
- measured in terms of species diversity, ecosystem diversity, and genetic diversity

Question 2

What is species diversity

Answer 2

Number of species in a community

Question 3

What is ecosystem diversity

Answer 3

Range of different habitats

Question 4

Define community

Answer 4

All the different species that live in one area and interact with each other

Question 5

How do u calculate index of diversity

Answer 5

d = N(N-1)/ sum of n(n-1)

N = total number of organisms of all species

n = total number of organisms of each species

Question 6

What impact does agriculture have on species diversity

Answer 6

Decreases series richness
- farmland is typically used for only 1 spaces (monoculture)
- use of pesticides and herbicides

Question 7

What impact does farming have on genetic diversity

Answer 7

Decrease
- farmers select for certain characteristics, which reduces number of different alleles in the population

Question 8

How can biodiversity be increased in areas of agriculture

Answer 8

• use hedgerows instead of fences
• grow different crops in the same area
