Answer 4

Comprises the number of different species in an ecosystem and the proportion of each species in the ecosystem

Question 5

Species richness

Answer 5

Number of different species

Question 6

Relative abundance

Answer 6

Proportion of each species in the ecosystem

Question 7

Answer 7

D=N(N-1)/En(n-1]
D = Diversity index
N = total number of individuals of all species
n = number of individuals per species
E = sum of

Question 8
