Answer:
i).A fruit is green in colour when unripe as its skin contains chloroplasts. When the fruit ripens, the chloroplasts are changed to chromoplasts which render an attractive colour to the fruit such as orange, yellow etc.
(ii) The colour of the fruits attracts animals and they come to feed over them.
(iii) While eating the fruits, the animals pick up the seeds and take them to different places which helps in the dispersal of seeds. Thus, both the animals and the plants are benefitted because of this. This is called mutualism.
(iv) Even in human society, nobody can live all by himself/herself. Everybody is dependent on somebody else for most of their activities. For example – a cook cooks food for you pay the cook so that he/she is able to run his/her family.
