What are ammonotelic animals give examples?
An ammonotelic organism excretes nitrogenous waste as soluble ammonia. Most of the aquatic animals including protozoans, crustaceans, platyhelminths, cnidarians, poriferans, echinoderms, fishes, larvae / tadpoles of amphibians are ammonotelic.
Is Tadpole of frog is carnivorous?
The life cycle of all amphibians involves a larval stage that is intermediate between embryo and adult. Tadpoles of frogs are mostly herbivorous, while tadpoles of salamanders and caecilians are carnivorous.
Is frog an ammonotelic animal?
Since, frogs excrete ammonia, they are known as ammonotelic.
Is tadpole larva Uricotelic?
A tadpole is the larval stage in the life cycle of an amphibian, particularly that of a frog or toad. Animals excreting their nitrogenous waste in the form of ammonia are known as ammonotelic (examples: aquatic invertebrates, bony fishes and aquatic amphibians). So, the correct answer is ‘Ammonotelic’.
Which is ureotelic animal?
Ureotelic animals – Animals that excrete urea in the form of waste are called ureotelic animals. Urea is less harmful than ammonia and requires less water for excretion. Examples: Few bony fishes, adult amphibians, fish, cartilaginous fish, and mammals including humans are ureotelic.
Why protozoans are called ammonotelic?
It is a very toxic substance to tissues and extremely soluble in water. For the excretion of ammonia (NH3), a large amount of water is required. The marine organisms that excrete ammonia into the water are called ammonotelic. Protozoans, echinoderms, poriferans, cnidarians, etc.
Do ammonotelic animals have kidneys?
Typically, aquatic anurans excrete ammonia (ammonotelic), because conserving water is not important. Uric acid–excreting animals (uricotelic) have the least contact with water (e.g., the tree frog). Amphibians have mesonephric kidneys and cannot concentrate urine above the solute concentration of the plasma.
Which animal is not uricotelic?
So, the correct answer is ‘Birds/Snake’.
