    1. Ingestion: The process of taking in food.
    2. Digestion: the process, the larger food particles are broken down into smaller, water-soluble particles.  There are physical or chemicals for digesting food.
    3. Absorption: The digested food is absorbed in the bloodstream through the intestinal wall.
    4. Assimilation: The absorbed food is used for energy, growth and repair of the cells of the body.
    5. Egestion: The undigested food is removed from the body in the faeces. This process is known as egestion.
    Whereas, cooking of food is not included in animal nutrition. Food is cooked on flame outside the body of the animal. 
    So, the correct answer is option B.

    Solution
    Human teeth have two sets life during their life i.e, one temporary set(milk teeth) and one permanent set. A set of temporary milk or deciduous teeth replaced by a set of permanents or adult teeth. Such type of dentition is called diphyodont.
    So the correct answer is  'All of the above'.
  • Question 5

    Solution
    • Rumination is also called second chewing. 
    • Ruminant stomach: The stomach of a ruminant is divided into four chambers – the rumen, reticulum, omasum, and abomasum. 
    • The process of digestion is as follows: The food is chewed and swallowed quickly and passed into the first stomach called Rumen. The microorganisms help in breaking down the food. Digestive juices of the rumen partially digest the food. The partially digested food in the rumen is called cud. 

    So, the correct answer is 'cud'.
  • Question 6
    1 / -0
    Which of the following is not a ruminant?
    Solution
    • Ruminants are the mammals that have the ability to take nutrients from the plant-based food containing cellulose by fermenting it in a specialized stomach (rumen) prior to digestion with the help of microbes. Buffalo, cow and goat are ruminant animals. 
    • Dogs are not able to digest cellulose due to the lack of enzyme called cellulase and hence dogs are not ruminant.

    So, the correct answer is 'Dog '.
  • Question 7
    1 / -0
    The breakdown of complex components of food into simple ones is called as
    Solution
    Digestion is the process of conversion of complex food substances into simpler absorbable substances. It is carried out by our digestive system by mechanical and biochemical methods.
    So, the correct answer is 'Digestion'.
  • Question 8
    1 / -0

    Solution
    Human teeth have two sets of teeth during their life one temporary set of milk teeth and one permanent set. Once the milk teeth have replaced by permanents, then the permanent teeth are not going to replace again in life naturally after 12 years of age.
    So the correct answer is 'Permanent teeth".
  • Question 9

    So, the correct answer is 'Sucking'.
