Question

name the nitrogenous waste (ammonia, urea or uric acid) in each animal group given below.
Conidaria, playhalminthes , Nematoda, porifera, Insecta, mollusca, Fishes, Reptiles, birds, Arachnida and urochordata

please help me I have exam tomorrow ​

Answer 1

Answer:

The elimination of nitrogenous waste materials through mainly kidney in ... Eg:‐ Insects, land snail, reptiles and birds. 1. ... Urea is less toxic than ammonia and more toxic than uric acid.

Answer 2

Answer

The removal of harmful metabolic or nitrogenous wastes such as ammonia (NH₃), urea and uric acid from the body is called excretion.

The process of excreting ammonia is called Ammonotelism.

Urea excreting animals are called ureotelic animals.

Uric acid excreting animals are called uricotelic.

» Conidaria

Nitrogenous waste : Ammonia

Excretory Organ : Diffusion is done across the plasma membrane.

» Platyhelminthes

Nitrogenous waste : Ammonia and fatty acids

Excretory Organ : Diffusion is through plasma membrane and flame cells

» Nematoda

Nitrogenous waste : Ammonia

Excretory Organ : Diffusion is done across plasma membrane and excretory canals.

» Porifera

Nitrogenous waste : Ammonia

Excretory Organ : Diffusion is done through plasma membrane.

» Insecta

Nitrogenous waste : Ammonia in acquatic forms and uric acid in land forms

Excretory Organ : Malphighian tubules and adipocytes

» Mollusca

Nitrogenous waste : Ammonia in acquatic forms and uric acid in land forms

Excretory Organ : Kidney, Organ of bojanus and pericardial glands.

» Fishes

Nitrogenous waste : Ammonia or urea

Excretory Organ : Kidney and gills.

» Reptiles

Nitrogenous waste : Ammonia or urea

Excretory Organ : Kidney

» Birds

Nitrogenous waste : Uric acid

Excretory Organ : Kidney

» Arachnida

Nitrogenous waste : Uric acid, Ammonia and guanine.

Excretory Organ : Malphighian tubules and hepato pancreas.

» Urochordata
