Question

Read the paragraph and answer the questions:

Paddy is cultivated on a large scale in various states of South India. Paddy fields are frequently attacked by grasshoppers. Similarly, frogs are also present in large number in the mud of paddy fields, to feed upon grasshoppers and snakes are also present therein to feed upon their favourite food-frogs. However, if the frog population declines all of a sudden,

1. What will be effect on paddy crop?
2. Number of which components will increase?

Answer 1

1. The paddy crop will be damaged/infested, and its yield will decrease because, without frogs, grasshopper numbers rise and attack the fields.
2. The number of grasshoppers (primary consumers) will increase. At the same time, tertiary consumers (snakes) will decline due to the loss of their frog food.
