excretory-products

#1

During the biology class, teacher taught that water should be conserved because it is precious and non-renewable in some cases. He asked the student that how the nature conserves water even through the excretory system of different organisms.
(i) Name three major excretory products of animals.
(ii) Does loop ofHenle play any role in water conservation ?
(iii) Explain excretory organs in different animal groups.
(iv) What values does the teacher possess?


#2

(i) Ammonia, urea and uric acid.
(ii) Yes, the amount of water expulsion depends upon the length of the loop of Henle (i.e., both are inversely proportional to each other).
(iii) Different animal groups present a variety of excretory structures (organs) to perform the process of excretion. In most of the invertebrates, these are simple tubular forms whereas, vertebrates have complex tubular organs called kidneys.
(iv) The teacher is very responsible towards his duty and he is trying to incorporate good values among his students.
