Differentiate between (i) insecticides and weedicides

(ii) Marine fisheries and inland fisheries

URGENT PLZ !!!

Insecticides are the chemical substances sprayed on crops to kill any insects feeding on them which can damage crops whereas weedicides are the chemical substances sprayed on the crops to kill the nearby weeds or unwanted plants which compete with the main crop for light, space and nutrition and may degrade quality and yield of the crop.

In inland fisheries, fishes are produced in fresh water systems like estuaries, lagoons etc.

In marine fisheries, fishes are produced in marine or sea waters.
