The reason why frogs lay so many eggs is to increase the chances of survival for the hatchlings, because they have many predators such as snakes, birds and turtles to eat them up.
Because external fertilization takes place in frogs and fishes and in external fertilization there is a high risk
many eggs get vanished due to action of wind, water,predators etc. so if they lay less eggs then fertilization does not takes place.
