Also called a fish maw or gas bladder the swim bladder is a gas-filled bladder that allows many bony fish to control their buoyancy by filling or releasing gas form the bladder. This allows them to change bouyancy without wasting metabolic energy by swimming.
Answer is Biogeochemical cycles.
In an ecosystem biotic (living) abiotic (non-living) components constantly interact each other. During these interactions, there is a transfer of nutrients between living organisms and the non-living environment. Thus, there is recycling of inorganic matter between living organisms and their non-living environment. This cycling of matter is called biogeochemical cycles.
