Q.

Define- nutrition, autotrophs.

Q. Case: Neena was writing a project report on nutrition in different organisms. A study on the digestive system of different animals showed that the length of the food pipe or oesophagus in different animals are different. The study showed that herbivores have a longer small intestine as compared to carnivores. Help Neena to complete her report by answering the following question:

Name the enzyme that is released by the gastric glands of the stomach.

1. Trypsin
2. Pepsin
3. Lipase
4. Ptyalin

Q.

Which of the following has the longest small intestine ?
(a) carnivore (b) omnivore (c) herbivore (d) autotroph

Q. Why are small intestines longer in herbivores as compared to carnivores?

[0.8 Mark]

1. The process of digestion in herbivores is slow compared to that in carnivores.
2. Cellulose takes more time to get digested as compared to meat.
3. Herbivores do curdling of food.
4. Herbivores have less efficient enzyme secretions.

Q. Match the following.

1. Gizzard
2. Ruminant
3. Green pellet
4. Dead meat

Q. Case: Neena was writing a project report on nutrition in different organisms. A study on the digestive system of different animals showed that the length of the food pipe or oesophagus in different animals are different. The study showed that herbivores have a longer small intestine as compared to carnivores. Help Neena to complete her report by answering the following question:

Why do herbivores have a longer small intestine than carnivores?

1. Herbivores consume more food than carnivores.
2. Herbivores consume simple sugar that is difficult to digest.
3. Herbivores consume grass that is rich in cellulose.
4. Carnivores consume meat that is difficult to digest.

Q. Define nutrition what are the different types of Nutrition found in living organism give example for each

Q. Case: Neena was writing a project report on modes of nutrition in different organisms. Heterotrophic organisms display three modes of nutrition i.e., saprophytic, parasitic and holozoic. In the holozoic mode of nutrition, a study on the digestive system of different animals showed that the length of the food pipe or oesophagus in different animals are different. The study showed that herbivores have a longer small intestine as compared to carnivores. Help Neena to complete her report by answering the following question:

Why do herbivores have a longer small intestine than carnivores?

1. Herbivores consume more food than carnivores.
2. Herbivores consume simple sugar that is difficult to digest.
3. Herbivores consume grass that is rich in cellulose.
4. Carnivores consume meat that is difficult to digest.

Q. (a) Why is the small intestine in herbivores longer than in carnivores ?

Q.

Type of heterotrophic nutrition adopted by animals depend mainly on

1. Type and availability of food material.

2. The way by which food is obtained/ accessed by an animal.

3. Kind of digestive system available in an animal (eg., cow or a lion).

4. All of these.

Q. Is ‘nutrition’ a necessity for an organism? Explain.

Q. what are the types of heterotrophic nutrition

Q. Why do herbivores have a longer small intestine than carnivores?

Q. Herbivores have a small intestine while carnivores have a one.

1. longer
2. shorter
3. narrower
4. broader

Q. Difference between heterotrophic and autotrophic nutrition

Q. The differences in the mode of heterotrophic nutrition in fungi, parasites, and mammals can be attributed to:

Q. Which of the following has the longest digestive tract ?

1. Carnivore
2. Herbivore
3. Omnivore
4. Autotrophs

Q. The differences in the mode of heterotrophic nutrition in fungi, parasites, and mammals can be attributed to:

1. Difference in body design
2. Availability of food
3. Similarity in digestive organs
4. Type of food
