Q. A certain ecosystem has a carrying capacity of 1,000 deer. If the current population is 800, what percentage of the carrying capacity is currently being utilized?
Q. A certain ecosystem has a carrying capacity of 500 rabbits. If the current population is 300 rabbits, what percentage of the carrying capacity is currently being utilized?
Q. A certain species of fish can reproduce every 3 months. If a single fish reproduces 20 offspring each time, how many fish will there be after 1 year assuming all offspring survive?
A.
80
B.
100
C.
120
D.
140
Solution
In 1 year (12 months), there are 4 reproduction cycles. Total fish = 1 + 4 * 20 = 81.
Q. A city has a population of 1 million people and each person contributes 4 tons of CO2 annually. What is the total CO2 contribution of the city in a year?
Q. A city plans to reduce its water consumption by 15% from its current usage of 2 million liters per day. What will be the new daily water consumption?
A.
1.7 million liters
B.
1.8 million liters
C.
1.9 million liters
D.
2 million liters
Solution
New consumption = Current usage - (15% of Current usage) = 2,000,000 - (0.15 * 2,000,000) = 2,000,000 - 300,000 = 1,700,000 liters.
Q. A conservation project costs $1.5 million and is expected to increase biodiversity by 25%. If the current biodiversity index is 40, what will be the new index?
A.
50
B.
45
C.
55
D.
60
Solution
New biodiversity index = Current index + (25% of Current index) = 40 + (0.25 * 40) = 40 + 10 = 50.
Q. A country aims to plant 1 million trees in 5 years. If they plant 200,000 trees in the first year, how many trees do they need to plant in the next 4 years to meet their goal?

800,000 trees
B.
600,000 trees

Solution
Trees remaining = Total goal - Trees planted in first year = 1,000,000 - 200,000 = 800,000. Average per year = 800,000 / 4 = 200,000.
Q. A country aims to reduce its carbon emissions by 25% over the next 5 years. If the current emissions are 200 million tons, what will be the target emissions after 5 years?
