CONTENT:  1. Classification based on the habitat 

                   2. Classification based on mode of reproduction and feeding of

              their  young ones.

Introduction:   Farm animals can be classified into different classes using different criterial.        These includes; their sizes, their habitat ,how they reproduce and feed their young ones and the type of stomach they have.

Sub-topic one: Classification Based On Their Habitat

Habitat means where someone or something is living. Some farm animals are living on land and we called them terrestrial animals. Example of such animals are: cattle, sheep, goats, pigs fowls camels etc. Some other farm animals live in water and are called aquatic animals. E.g. fish  shellfish, hippopotamuses etc.

          There are some terrestrial animals, however, that live on trees and are called arborial  animals e.g.  birds.

           All living things need oxygen for survival. Terrestrial animals obtain oxygen directly from the atmosphere, but aquatic animals obtain oxygen dissolved in the water where they live.


1.   What are terrestrial animals?

2.   Give four examples of the following:


Aquatic animals.

Terrestrial animals.

3.   Where does the aquatic animals get their oxygen requirement?

2.   Mention five examples each of each

3.   State three characteristics of mammals.
