    This working reaches the answer NCERT prints. It has not yet been read through by hand.

    NCERT’s answer
    (d)
    (d) Gram. Rice, millets and sorghum are cereals rich in starch; a pulse like gram is valued for protein, not carbohydrate.

  3. Exercise 3

    Find out the wrong statement from the following
    (a)
    White revolution is meant for increase in milk production
    (b)
    Blue revolution is meant for increase in fish production
    (c)
    Increasing food production without compromising with environmental
    quality is called as sustainable agriculture
    (d)
    None of the above

    This working reaches the answer NCERT prints. It has not yet been read through by hand.

    NCERT’s answer
    (d)
    (d) None of the above. White Revolution raised milk output, Blue Revolution raised fish output, and the sustainable-agriculture statement is accurate too.

  4. Exercise 4

    To solve the food problem of the country, which among the following is
    necessary?
    (a)
    Increased production and storage of food grains
    (b)
    Easy access of people to the food grain
    (c)
    People should have money to purchase the grains
    (d)
    All of the above

    This working reaches the answer NCERT prints. It has not yet been read through by hand.

    NCERT’s answer
    (d)
    (d) All of the above. Solving hunger needs more grain grown and stored, easy access to it, and the money to buy it.

  5. Exercise 5

    Find out the correct sentence
    (i)
    Hybridisation means crossing between genetically dissimilar plants
    (ii)
    Cross between two varieties is called as inter specific hybridisation
    (iii)
    Introducing genes of desired character into a plant gives genetically
    modified crop
    (iv)
    Cross between plants of two species is called as inter varietal
    hybridisation

    This working reaches the answer NCERT prints. It has not yet been read through by hand.

    NCERT’s answer
    (a)
    (a) (i) and (iii). Hybridisation crosses genetically dissimilar plants; inserting a desired gene makes a genetically modified crop. (ii) and (iv) swap intervarietal and interspecific crossing.

  6. Exercise 6

    Weeds affect the crop plants by
    (a)
    killing of plants in field before they grow
    (b)
    dominating the plants to grow
    (c)
    competing for various resources of crops (plants) causing low availability
    of nutrients

    NCERT’s answer
    (c)
    (c) Competing for resources. Weeds share soil, water, light and space with the crop, leaving fewer nutrients for it and lowering yield.

    (a)
    Apis dorsata
    (b)

    It helps in draining out of excess of water from clayey soil.
    (iv)
    Its excessive use pollutes environment because it is made of animal
    excretory waste.

    NCERT’s answer
    (b)
