Why must the male provide an excess of gametes while the female does not?

In most species, males produce a larger number of gametes (sperm) because they are smaller and more mobile compared to eggs. This higher number of sperm increases the chances of successful fertilization as sperm must travel to the egg and compete with other sperm for fertilization. Females, on the other hand, invest more energy in producing larger, nutrient-rich eggs that are less mobile and need protection, hence the lesser quantity.

What happened doing fertilize?

If your question is what happens during fertilization? the answer varies. If your are speaking about sexual reproduction then fertilization occurs when the sperm and egg combine. Basically the first sperm to get to the egg keeps it. The egg hardens to keep excess sperm from entering. (of course some errors can occur which will lead to defects, twins, triplets, etc.) There are many other phases to the reproduction process but fertilization is basically when the egg and sperm combine.
