Question

why few aquatic organism store waste in their body and what is the reason to adopt such lifestyle, explain it w.r.t evolution​?

Answer 1

Answer:

Birds

Explanation:

Excretion is a process by which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life. For example, in mammals urine is expelled through the Birds have a chamber called a cloaca where digestive wastes, uric acid, and eggs or sperm go before leaving the body. While the uric acid is in the cloaca, birds can absorb some of the water back. ... Some sea birds can even drink sea water and excrete the extra salt out of glands near their eyes., which is part of the excretory system. In unicellular organisms, waste products are discharged directly

I Birds excrete their nitrogenous wastes as uric acid in the form of a paste. Although this process is metabolically more expensive, it allows more efficient water retention and it can be stored more easily in the eggs. Many avian species, especially seabirds, can also excrete salt via specialized nasal salt glands, the saline solution leaving through nostrils in the beak.

Answer 2

Some of the aquatic organism Store their waste temporally in their body because of the evolutionary trend with the lower group of organisms

Explanation:

• The waste is mainly stored in the form of of substances inside the vacuole of the cell. When there is excess there is removal of the waste.

• This helps in maintenance of the osmolarity in the body of the aquatic organism specially the saline organism. If there is no storage of waste then the polarity will decrease resulting in plasma lysis of the cells of the organ
