Why is no. of eggs, laid by frogs at a time, much higher than those laid by a hen
Answers
Life forms having inner fertilization, similar to a hen, deliver one just one egg during a stipulated time. This is in light of the fact that in this case, there is a minimal chance of fertilization of both the gametes. After treatment of the gametes, there is only the need of advancement of a creature as an egg.
Frog-like sea-going life forms who demonstrates an external method of generation needs to lay a hundred eggs. The principal explanation for this is that one single egg is so little that it won't be conceivable to remain in a clear position and which in turns make difficult for sperm to establish and intertwine them.
While, when a vast number of eggs allows them to stick together, this makes the process of fertilization conceivable. Another explanation for this is there is a considerable measure of living beings eating these eggs, so a bigger number of eggs gives a greater probability of bringing forth a large number of youthful ones.
