Food And Nutrition Quiz For 7 Grade - Quiz

Food is an essential part of our life and existence, isn't it? That is why we have brought the food and nutrition quiz for grade 7. Food and nutrition are two important ways that give us fuel and provide energy for our bodies. We always have the requirement of food to replace nutrients in our bodies with a new supply every day. Water comes under an important component of nutrition. Other than that, fats, proteins, and carbohydrates are all required. This quiz tests whether you understand food or nutrition well enough or not.


Questions and Answers
  • 1. 

    The process of breakdown of complex components of food into simpler substances is called _______.

    • A.

      Fabrication

    • B.

      Blood

    • C.

      Nutrition

    • D.

      Digestion

    Correct Answer
    D. Digestion
    Explanation
    Digestion is the correct answer because it refers to the process of breaking down complex components of food into simpler substances. This process occurs in the digestive system, where enzymes and acids break down carbohydrates, proteins, and fats into smaller molecules that can be absorbed and used by the body for energy and growth.

    Rate this question:

  • 2. 

    The ______ helps in mixing saliva with food.

    • A.

      Tongue

    • B.

      Teeth

    • C.

      Bladder

    • D.

      Kidney

    Correct Answer
    A. Tongue
    Explanation
    The tongue helps in mixing saliva with food. The tongue is a muscular organ located in the mouth that plays a crucial role in the process of digestion. It aids in the movement of food within the mouth, helps to shape and position the food for chewing, and mixes the food with saliva, which contains enzymes that begin the process of breaking down carbohydrates. The tongue also helps in swallowing by pushing the food towards the throat.

      Starfish

    • D.

      Catfish

    Correct Answer
    C. Starfish
    Explanation
    Starfish is the correct answer because it is a marine animal that is covered by hard shells of calcium carbonate, known as exoskeletons. Additionally, starfish have a unique mode of nutrition called "extracellular digestion." They have a specialized stomach that can be everted and pushed out of their body to engulf and digest prey outside of their body.

    Rate this question:

  • 4. 

    The _________ present in the buccal cavity cut the food into small pieces by chewing and grinding it.

    • A.

      Nose

    • B.

      Teeth

    • C.

      Lips

    • D.

      Eyes

    Correct Answer
    B. Teeth
    Explanation
    Teeth are present in the buccal cavity and their main function is to cut the food into smaller pieces by chewing and grinding it. The teeth have a hard enamel covering that allows them to exert force on the food, breaking it down into smaller, more manageable pieces for digestion. The shape and arrangement of the teeth are specifically designed for this purpose, with different types of teeth serving different functions in the chewing process.

    Rate this question:

  • 5. 

    The stomach’s inner lining produces three things: • __________________: It protects the lining of the stomach from harmful effects of HCl. • ___________________: The acid kills many bacteria that enter along with the food and makes the medium in the stomach acidic.  ________________: They help in digestion of the food by breaking down the proteins present in the food into simpler substances.(Choose the correct answers)

    • A.

      Mucous

    • B.

      Anus

    • C.

      Stomach

    • D.

      Hydrochloric acid

    • E.

      Pancreas

    • F.

      Digestive juices

    Correct Answer(s)
    A. Mucous
    D. Hydrochloric acid
    F. Digestive juices
    Explanation
    The stomach's inner lining produces mucous, which protects the lining from the harmful effects of hydrochloric acid. Hydrochloric acid is produced in the stomach and helps kill bacteria that enter along with the food, as well as making the stomach acidic. Digestive juices are also produced in the stomach and help break down proteins in the food into simpler substances during digestion.

    Rate this question:

  • 6. 

    There are three glands associated with the alimentary canal that secrete digestive juices that are used to convert complex food substances into simpler substances.(Check them)

    • A.

      Liver

    • B.

      Pancreas

    • C.

      Salivary gland

    • D.

      Anus

    Correct Answer(s)
    A. Liver
    B. Pancreas
    C. Salivary gland
    Explanation
    The correct answer is Liver, Pancreas, and Salivary gland. These three glands are associated with the alimentary canal and secrete digestive juices. The liver produces bile, which helps in the digestion and absorption of fats. The pancreas secretes pancreatic juice, which contains enzymes that break down carbohydrates, proteins, and fats. The salivary glands produce saliva, which contains enzymes that initiate the digestion of carbohydrates in the mouth. The anus is not a gland associated with the secretion of digestive juices.

    Rate this question:

  • 7.

    • A.

      Mouth or buccal cavity

    • B.

      Liver

    • C.

      Food pipe or esophagus

    • D.

      Pancreas

    • E.

      Stomach

      Anus

    Correct Answer(s)
    A. Mouth or buccal cavity
    C. Food pipe or esophagus
    E. Stomach
    F. Small intestine
    H. Large intestine
    I. Anus
    Explanation
    The given answer includes all the correct parts of the canal. The mouth or buccal cavity is where the digestion process begins as food enters the body. The food pipe or esophagus is responsible for transporting food from the mouth to the stomach. The stomach is where food is further broken down by stomach acids. The small intestine is where most of the digestion and absorption of nutrients takes place. The large intestine is responsible for absorbing water and electrolytes from the remaining food material. The anus is the final part of the canal where waste material is eliminated from the body.

  • 8. 

    Tooth decay is caused mainly because of eating food with high ________ content, _________and ________________.(check the correct options)

    • A.

      Sugar

    • B.

      Chilies

    • E.

      Chocolates

    Correct Answer(s)
    A. Sugar
    D. Soft drinks
    E. Chocolates
    Explanation
    Tooth decay is primarily caused by consuming foods that are high in sugar content, such as soft drinks and chocolates. These sugary foods provide a breeding ground for bacteria in the mouth, which produce acids that attack the tooth enamel, leading to decay. Chilies and junk food are not directly linked to tooth decay as they do not contain high sugar content.

      Dental floss

    Correct Answer(s)
    A. Brush
    E. Dental floss
    Explanation
    The correct answer is "Brush, Dental floss" because brushing and using dental floss are both effective ways to clean teeth. Brushing helps remove plaque and food particles from the surface of the teeth, while dental floss helps clean the areas between the teeth where a toothbrush cannot reach. Both brushing and flossing should be done at least twice a day to maintain good oral hygiene.

  • 11. 

    The pancreatic juice acts on _______________ and ________________ and changes them into simpler forms. 

    • A.

      Fats

    • B.

      Carbohydrates

    • C.

      Acids

    • D.

      Proteins

    Correct Answer(s)
    B. Carbohydrates
    D. Proteins
    Explanation
    Pancreatic juice contains enzymes such as amylase and trypsin that act on carbohydrates and proteins respectively. Amylase breaks down carbohydrates into simpler forms such as glucose, while trypsin breaks down proteins into amino acids. This process of digestion allows the body to absorb and utilize these nutrients more efficiently.

    A. Hiccups,
    C. Cough
    D. Choking
    Explanation
    When we laugh or talk while eating, the windpipe remains open, allowing food particles to enter it. This can lead to various symptoms such as hiccups, coughing, and choking. These symptoms are the body's way of clearing the blockage in the windpipe caused by the food particles.
