Fertilization means sex. Development is what makes the belly start to get big.
I think you can figure it out.

Fertilization is the process when gametes unite and form a zygote. The sperm fertilizes the egg in many species of animals, while in plants the sperm nuclei will enter the embryo sac and fertilize the egg and the two polar nuclei.
Development follows and is an on going process until the death of the organism.

Fertilization is the process of the two gametes joining together. The egg joins with the sperm.
Development is what happens after the zygote divides and the cells begin to form the parts of the new organism.
Fertilization is first.
