Several systems do this function, the kidneys, the respiratory tract, the lower digestive tract and the skin.
Most nitrogenous wastes in living organisms originate from the breakdown of proteins and nucleic acids during metabolism. These wastes are then excreted from the body through processes like urine formation in mammals and ammonia excretion in fish.
hazardous wastes
By breaking down the dead organisms or wastes of other living things.
hazardous wastes
Wastes would accumulate in ecosystem .
Organisms remove metabolic cellular wastes by the process of excretion.
The function of the digestive system is to remove wastes from the body.
Offspring and wastes.
Decomposers are the organisms that break down the wastes and remains of other organisms.
Materials that living organisms can't use are excreted from the body as wastes. Elimination or excretion methods vary from species to species; humans and many other animals get rid of wastes mainly through urination and defecation.
This process is known as biomagnification. Industrial wastes accumulate in organisms as they are consumed by predators, leading to higher concentrations of these toxins in animals higher up in the food chain. This can have detrimental effects on the health of these top predators.
Wastes that can be broken down by other organisms into a reusable form are called "biodegradeable" The list of biodegradable wastes is extremely long.
