Case Study Questions on Nutrition in Animals
Questions
Question 1:
Read the given passage below and answer the question:
The small intestine is highly coiled structure. It is about 7.5 metres long. It receives secretions from the liver and the pancreas. The liver is a reddish brown gland located in the upper part of the abdomen on the right side. The pancreas is a large cream coloured gland located just below the stomach that secretes the pancreatic juice.
Q.1. The liver releases:
(a) digestive juice
(b) acid
(c) bile juice
(d) saliva
Difficulty Level: Easy
Ans. Option (c) is correct
Explanation: The liver secretes bile juice that is stored in a sac called the gall bladder
Q.2. The glands associated with the alimentary canal are:
(a) salivary glands and liver
(b) pancreas and liver
(c) gall bladder and liver
(d) salivary glands, liver and pancreas
Difficulty Level: Medium
Ans. Option (d) is correct.
Explanation: The various glands associated with the canal such as salivary glands, the liver and the pancreas secrete digestive juices. The salivary glands present in the buccal cavity secret saliva. Saliva helps in the digestion of starch. Bile is secreted by the liver however, stored in gall bladder and pancreatic juice is secreted from the pancreas.
Q.3. In the lower part of the small intestine which juice completes the digestion of all components of the food.
(a) saliva
(b) bile
(c) pancreatic
(d) intestinal juice
Difficulty Level: Medium
Ans. Option (d) is correct.
Explanation: The partly digested food on reaching the lower part of the small intestine where the intestinal juice secreted by the inner walls of the intestine, completes the digestion of all components of the food.
Q.4. What important function of pancreatic juice and bile.
Difficulty Level: Medium
Ans. The pancreatic juice acts on carbohydrates, fats and proteins and changes them into simpler forms.
The bile plays an important role in the digestion of fats.
Q.5. What happens when the partly digested food reaches the lower part of the small intestine.
Difficulty Level: Difficult
Ans. When the partly digested food reaches the lower part of the small intestine, then the intestinal juices completes the digestion of all components of the food.

Q2: Why are case study questions important for understanding class 7 science chapters?
A2: Case study questions provide a practical context for students to apply theoretical knowledge to real-world situations, fostering deeper understanding and critical thinking skills.
Q3: How should students approach answering case study questions for CBSE?
A3: Students should carefully read the case study, identify the key issues or problems presented, analyze the information provided, apply relevant concepts and principles, and formulate well-supported solutions or responses.
Q4: Are there any resources available online for students to practice case study questions on class 7 science chapters for CBSE exams?
A4: Yes, several educational websites offer case study questions for CBSE students preparing for science examinations. We also offer a collection of case study questions for all classes and subject on our website. Visit our website to access these questions and enhance your learning experience.
Q5: How can students effectively prepare for case study questions on nutrition in animals for CBSE exams?
A5: Effective preparation strategies include regular revision of concepts, solving practice questions, analyzing case studies from previous exams, seeking clarification on doubts, and consulting with teachers or peers for guidance and support.
Q6: How can teachers incorporate case study questions on nutrition in animals class 7 science into classroom teaching?
A6: Teachers can integrate case studies into lesson plans, group discussions, or interactive activities to engage students in active learning, promote problem-solving skills, and facilitate a deeper understanding of nutrition in plants.
Q7: What is the process of nutrition in animals?
A7: Nutrition in animals involves the intake, digestion, absorption, and utilization of food to obtain energy and essential nutrients required for growth, maintenance, and repair of body tissues.
Q8: What role do enzymes play in the process of digestion in animals?
A8: Enzymes are biological catalysts that facilitate chemical reactions in the digestive system by breaking down complex food molecules into simpler substances that can be absorbed by the body. Different enzymes act on specific types of food molecules.
Q9: How does the process of digestion occur in the stomach of animals?
A9: In the stomach, food is mixed with gastric juices containing hydrochloric acid and enzymes like pepsin. The acidic environment helps in the breakdown of proteins, while muscular contractions churn the food, converting it into a semi-liquid form called chyme.
