Answer:
Fish and frogs have to lay a lot of eggs because it's dangerous in the wild and more babies increases the chances of survival for the species.
Step-by-step explanation:
If humans were to do the same and have many babies at once, the world would become overpopulated very quickly as there aren't any predators or natural threats to humans, we aren't being killed off one by one by a wide array of predators like fish and frogs, who are normally prey animals on the food chain.
