Question

1)what are primitive organisims? give examples.

2)what are advanced organisms . give examples

3)write the difference between primitive and advanced organisms

Answer 1

Primitive organisms :- The organisms which have ancient body textures that                                        have not changed so much, are known as primitive                                          organisms.

Advanced organisms :- The advanced organisms are those which have                                               acquired their specific body designs relatively                                                 recently.


Difference between primitive and advanced organisms :- As per the body                                                                      designs, the primitive organisms                                                             have simple structures whereas the                                                              advanced organisms have some more                                              complex structures.

Answer 2

Hi there !
______________________________________________________________

primitive organisms - these are organisms which emerged in ancient time with simple body structure
____________________________________________________________


advanced organisms- these are advanced organisms with complex body structure that evolved recently.

____________________________________________________________
Difference-
primitive organisms:- 1) they have simple body structure
                                  2)they evolved in ancient times
                                  3) they are less evolved and their body work is simple.


advanced organisms- 1) they have complex body structure
                                   2)  they evolved recently 
                                   3) they can change over evolutionary time
