What is ureotelic & uricotelic?

Question

Answer

UREOTELIC:-1.A ureotelic organism excretes excess nitrogen as urea. It is one of the three major forms of excretion of nitrogenous waste in organisms, the others being ammonotelism and uricotelism.2.Urea is less toxic than the ammonia excreted by ammonotelic organisms.URICOTELIC:-1.Animals that excrete a major portion of nitrogenous waste in the form of semi-solid or solid uric acid are called uricotelic animals.2.e.g. birds, lizards, snakes, terrestrial insects.

Answer

Ureotelic animals..-in this excess nitrogen is excreted as urea..n in uricotelic animals..-urea is given out in form of semi solid..like lizard..

Answer

Ureotelic Organisms
Ureotelic organisms primarily excrete nitrogenous waste in the form of urea. This mechanism is crucial for maintaining water balance and minimizing toxicity.

Examples: Mammals, amphibians, and some reptiles.
Process: Urea is synthesized in the liver through the urea cycle, where ammonia is converted to urea, which is less toxic and more water-soluble.
Water Conservation: Ureotelic organisms can conserve water, making them well-adapted to terrestrial environments.

Advantages of Ureotelism

Reduced Toxicity: Urea is less toxic than ammonia, allowing for safe storage and transport.
Efficient Water Use: Urea excretion requires less water compared to ammonia, aiding survival in arid conditions.

Uricotelic Organisms
Uricotelic organisms excrete nitrogenous waste primarily as uric acid. This adaptation is especially advantageous in environments where water conservation is critical.

Examples: Birds, reptiles, and most terrestrial arthropods.
Process: Uric acid is produced in the liver and excreted as a paste, minimizing water loss.
Water Efficiency: Uric acid is insoluble in water, allowing organisms to excrete nitrogenous waste with minimal water loss.

Advantages of Uricotelism

Extreme Water Conservation: Ideal for organisms in arid environments, as it conserves significant amounts of water.
Less Toxic Waste: Uric acid is less toxic than ammonia, allowing for safe accumulation until excretion.

Understanding these two methods of nitrogenous waste excretion highlights the diverse adaptations in the animal kingdom, enabling survival across various habitats.
