A.
60%
B.
70%
C.
75%
D.
80%
Solution
(750 / 1000) * 100 = 75% of the carrying capacity.

A.
70%
B.
75%
C.
80%
D.
85%
Solution
(800 / 1000) * 100 = 80% of the carrying capacity.
Q. A certain ecosystem has a carrying capacity of 300 animals. If the current population is 240, what percentage of the carrying capacity is currently utilized?
A.
60%
B.
70%
C.
80%

A.
1/5
B.
3/5
C.

A.
80
B.
160
C.
320
D.
640
Solution
3 years = 6 periods of 6 months. 20 offspring * 6 = 120 fish + 1 original = 121 fish.

A.
10%
B.
15%
C.
20%
D.
25%
Solution
To double the population in 5 years, the annual growth rate must be approximately 25%.
Q. A conservation program aims to increase the population of an endangered species by 25% each year. If the current population is 400, what will be the population after 2 years?
A.
500
B.
600
C.
625
D.
700
Solution
After 1 year: 400 + (25% of 400) = 500; After 2 years: 500 + (25% of 500) = 625.
Q. A researcher finds that a certain plant species has a growth rate of 5 cm per month. How tall will the plant be after 2 years if it starts at 10 cm?
A.
70 cm
B.
80 cm
C.
90 cm
D.
100 cm
