The given blank can be filled with the population.
In the basic terms, when a habitat is destructed, then the animals, plants, and other species, which are thriving in a habitat exhibit a diminished carrying capacity. This further results in the decline of populations and thus extinction becomes more expected. Therefore, it can be stated that the greatest danger to organisms and biodiversity is the procedure of habitat loss.

Answer:
Density is nearly 3 cabs per hectare
Explanation:
Given -
There are three three intertidal regions.
Area of each intertidal region is 
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
Total area of all three intertidal regions is equal to
hectares
Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions
Density 
Density is nearly 3 cabs per hectare
