Final answer:
Electric eels, which are an example of electrogenic fish, generate electric discharges using electroplaques. These discharges can stun or kill prey and are detected by electroreceptors. Weakly electric fish have both organs to generate electric discharges and electroreceptors.
Step-by-step explanation:
Electric eels, which are an example of electrogenic fish, generate electric discharges using organs called electroplaques.
These electroplaques produce an electric field which is then detected by electroreceptors in the eel's skin. However, not all fish that generate electricity have electroreceptors.
Therefore, the statement 'Weakly electric fish have organs to generate electrical discharge, but do not have electroreceptors' is false.
