Starting from the outer part:
•Tunica externa (fibrous layer)

Freshwater fish might have urinary tract and kidney disease if they would not be able to produce lots of watery urine. This will result to parasite infestation. To avoid this, the freshwater fish will have to pee or urinate. Their pee or watery urine consists of ammonia and other organic acids like creatine and creatinine.
A moving cycle will have Kinetic energy which converts into potential energy when it is at rest.
Lets see...
Exhaustible Resources ~ An exhaustible resource is any source of energy that is limited and cannot be replaced when it is used, such as oil, coal, and natural gas.
Inexhaustible Resource ~ An inexhaustible resource is a source that will never run out, like, solar energy. So, Solar energy is out. Wind energy is out. Hydroelectric energy is out. Geothermal energy is out.
So, Biomass energy is not considered inexhaustible.
