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
![7 + 2+ 6\\= 15](https://tex.z-dn.net/?f=7%20%2B%202%2B%206%5C%5C%3D%2015)
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 ![= \frac{15}{6} \\= 2.5](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B15%7D%7B6%7D%20%5C%5C%3D%202.5)
Density is nearly 3 cabs per hectare
Answer:
Swim bladder
Explanation:
Swim bladder is an organ in bony fishes such as catfish that controls their buoyancy. It is also known as air bladder. The swim bladder contains gas, mainly oxygen and functions as a hydrostatic organ.
As the fish moves in deeper water, the gas in the swim bladder is contracted which decreases the volume of swim bladder.
