Question

Pickles do not spoil but sambar get spoil why
farmers are afraid of unseasonal rains and uncontrolled pest how

Answer 1

Pickle is very concentrated as it has very low water content than spoiling bacteria. since water flowes always from higher concentration to lower concentration so water from insect body comes out ans plasmolysis takes place leads to death of bacteria. hence pickle does not spoil but sambar spoils.
Rain is factor which is only suitable in its perfect season.unseasonal rain leads to loss of farmers crops and pests leads to disease and death of crops.
