If an isolated population’s birthrate is the same year after year, why are a greater number of individuals added to the population in each successive year? A) The effective birthrate is increasing each year.

B) The carrying capacity is increasing each year.

C) The rate applies to more individuals each year.

D) Fewer members emigrate away each year.

C) The rate applies to more individuals each year.

Explanation:

Suppose the initial population was 200 people and birth rate was 10% of that. So thats 0.10 * 200= 20 babies that year.

Next year the population is 200+ 20 = 220 people. Now if the birth rate is still 10% then you will have 0.10 * 220 = 22 babies that year.

Did you see that? The number of babies increased by 22-20= 2 extra babies each year.

Therefore, since rate applies to more individuals each year, you'll get increase in population

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
