Questions & Step-by-Step Solutions
If a coral reef can support 50 species of fish per square kilometer, how many species can be supported in a reef that is 5 square kilometers?
Step 1: Understand that the coral reef can support 50 species of fish in 1 square kilometer.
Step 2: Identify the size of the reef, which is 5 square kilometers.
Step 3: To find out how many species can be supported in 5 square kilometers, multiply the number of species per square kilometer (50) by the total area of the reef (5).
Step 4: Perform the multiplication: 50 species/km² * 5 km² = 250 species.
Step 5: Conclude that the reef can support a total of 250 species of fish.
Multiplication of Rates – Understanding how to apply a rate (species per area) to a larger area to find the total.
