Question

Fourteen Grey wolves were introduced into Yellowstone in 1995. By the end of 1997, there were 100 wolves in Yellowstone, and by 2002, there were 275 reported. If their population growth continued at the same rate and the population is not limited by any carrying capacity due to the environment, based on the popion values in the Syear period between 1997 and 2002, grey wolves would you predict to see 10 years later in 2012?
a. 756
b. 175
c. 2,080
d. 625
e. 450
f. 5,720

Answer 1

Answer:

d) 625 grey wolves

Explanation:

Number of grey wolves in yellowstone;

1997 = 100 wolves

2002 = 275 wolves

Between 1997 and 2002 (a five year period), number of wolves increased by; 275 - 100 = 175 wolves

Population growth rate between 1997 and 2002 = 175 wolves per 5 years

Note that the population growth continued at the same rate from 2002 to 2012 (a ten year period).

Therefore;

if; 5 years = 175 wolves

10 years = (175 × 10) / 5 =350 wolves.

therefore, number of wolves between 2002 and 2012 = 350 wolves.

Number of wolves as at 2002 = 275 wolves

total number of wolves at 2012 = 350 + 275 = 625 wolves
