A marine ecologist counts the number of crabs in three different intertidal regions that are each two hectares. The crab counts

romanna [79]

Answer:

Density is nearly 3 cabs per hectare

Explanation:

Given -

There are three three intertidal regions.

Area of each intertidal region is $2$ hectares.

Number of crab in the intertidal regions are as follows -

Intertidal region I - 7

Intertidal region I - 2

Intertidal region I - 6

Sum of crabs in all three regions is equal to

$7 + 2+ 6\\= 15$

Total area of all three intertidal regions is equal to

$2 + 2+ 2\\= 6$ hectares

Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions

Density $= \frac{15}{6} \\= 2.5$

Density is nearly 3 cabs per hectare
