Water is composed of two elements known as hydrogen and oxygen. It is two molecules of hydrogen to a molecule of oxygen in percentage.
We cannot fully comprehend the fullness of life without the importance of water to living things. There is this adage in Nigeria that say water has no enemy. How true this word is can be seen right through the pages of the bible and our everyday activities. Historically, water serves as a means or instrument of purification. Although the scope of this article will not delve deep into the characters of a good water, uses of water at home, or the general importance of water to farmers in the scope of agriculture science.
Water can be hard or soft.
Water contain a lot of micro living organisms that can only be seen with the aid of a microscope.
For the intent of this article, the body of animals mostly humans consists of at least 70% water. Water can be found in the natural and artificial state and can be found everywhere. In fact, water is termed as the pivot of life itself. No water no life.
Let us take a look at the availability of water and its sources
SOURCES OF WATER
Sources of water available to animals include metabolic water from food, drinking water from tap, rivers, rain water and ponds.
IMPORTANCE OF WATER
The essential importance of water to animals are listed in the following ways
i. Water is required for metabolic activities in the body
ii. Water is necessary for the digestion of food
iii. Water can be used for the maintenance of body temperature
iv. Water is the main components of plants and animals. It forms about 75% of the body of humans
v. Water can act as solvent for soluble food substances in digestion
vi. Water serves as a medium of transportation for nutrients
vii. Water constitutes a greater part of blood
viii. Water helps to maintain the osmotic content of the body tissues
ix. Water is the basis of secretion from endocrine glands

Roughages consists of indigestible fibrous materials derived from vegetables, fruits, carbohydrates and proteins.
Roughages provide bulk to the intestinal content thereby stimulating the movement of bowel.
Lack of Roughages in the diet can cause constipation.
Roughages are easily digested by micro-organisms in the intestinal tract.
Here is a typical examples of the classes of food
1. VITAMINS=====fruits, vegetables, egg, milk, liver oil etc.
2. FAT=======groundnut, melon, butter, margarine, palm oil, soya bean oil and cod liver oil
3. WATER============Water in plants, water in animals, water in drinks, beverages and food
4. MINERAL SALTS========vegetables, fruits, bones, egg and table salt
5. CARBOHYDRATES=======Rice, bread, millet, cassava, yam, cocoyam, potato etc.
6. PROTEIN=========MEAT, BEANS, GROUNDNUT ETC.
