The abdominal cavity is lined by peritoneum. It is a membrane that covers the inner layer of the cavity and also the organs inside. The membrane on the inner wall is parietal Thperitonium and the membrane that lines the organ is called visceral peritoneum.  This helps in fixation and support of abdominal organs.

The fish is the limiting factor because its population <u>determines the survival and availability  of the grizzly bears.</u>
A limiting factor is  resources(biotic or abiotic) that affects or determine the availabity and growth of an organism or group of an organism within an ecosystem.
 The more fish it takes, the more the liver produces urea, and kidney tubules  makes use of the urea in it tubules for urine formation in the loop of Henle. The urine formation and loss, leads to intake of water and the sequence continues.
This is an example of a biological limiting factor because the bear  predate on the fish for survival and population.
If the population of the fish drops,( <u>the limiting facto</u>r) the bear drinks less water based on above, and therefore <u>disruptions  of the ecosystem</u>.
