उत्तर
(a) Seeds are spread by birds, animals, air, and water. Many animals eat fruit
and throw seeds. Thus these animals help in spreading seeds.
(b) Some seeds stick to the fur of animals and thus are transported to other places.
(c) Some seeds have thin hairs and are lightweight. These seeds float on air and travel to other places.
(d) Some seeds float on water and thus travel to far-off places.
