tangare [24]

Answer:

a) b + i = d + e

b) b + i < d + e

c) b + i > d + e

this means increase in population is equal to decrease in population

i.e

b + i = d + e

b) b) a declining population

this means increase in population is less than decrease in population

i.e

b + i < d + e

c) an increasing population

this means increase in population is increase in decrease in population

i.e

b + i > d + e
