Question

What are Ammonotellic, Ureotellic and Uricotelic animals?

Answer 1

Ammonotelic animals:

• The excretory matter in these animals is Ammonia

• They require a large amount of water.

• Excretion takes place by diffusion through gill surfaces as ammonium ions.

• The excretory matter is highly toxic.

• Examples:- Tadpoles

━━━━━━━━━━━━━━━━

Ureotelic Animals:

• The excretory matter is urea.

• They require less water as compared to ammonotelic animals.

• The urea is released into blood by the liver which is filtered and excreted out by kidneys.

• The excretory matter is less toxic than ammonia.

• Examples:- Mammals

━━━━━━━━━━━━━━━━

Uricotelic animals:

• The excretory matter is urea.

• They require very less amount of water.

• The excretory matter is least toxic

• Examples:- Birds

Answer 2

Answer:

❑❐HERE UR ANSWER✍ ❑❐

(1)✰Animals which excrete nitrogenous waste products in the form of ammonia are called ammonotelic animals. Examples: Bony fish, aquatic insects.

(2)✰A ureotelic organism excretes excess nitrogen as urea. Urea is less toxic and needs less water in comparison to Ammonia. The uricotelic organism excretes uric acid or its salts.

(3)✰Quick Reference. Describing animals that excrete nitrogenous waste in the form of uric acid. Uricotelic animals include birds and reptiles.
