The number of eggs an animal produces is related its form of fertilization and development because the more eggs there are, the more likely it is for one to be fertilized.
Depends on the animal, but in general male produces sperm, female produces eggs, and MAY hold fertilized eggs until they grow (but not always)
We can do this with animals as well. They are called hybrids. Some are not fertile. An example of an animal is a mule: a cross between female donkey and a male horse. A cross between a male donkey and female horse produces a hinny which is considered worthless.
After fertilization, the zygote undergoes cell division through mitosis. The daughter cells continue to divide and differentiate into various cell types, forming tissues, organs, and ultimately leading to growth of the organism. This process is regulated by genetic and environmental factors to ensure proper development and growth of the diploid animal.
Animal egg cells, or oocytes, are larger than most other cells in the body primarily due to their role in reproduction. They need to store essential nutrients, organelles, and genetic material to support the early stages of embryo development after fertilization. This larger size also facilitates the processes of fertilization and the subsequent development of the embryo, as it provides a suitable environment for these critical early stages.

The stages of early animal development in the correct order are: fertilization, cleavage, gastrulation, and organogenesis. Fertilization is the fusion of gametes to form a zygote, cleavage is rapid cell division of the zygote, gastrulation is the formation of germ layers, and organogenesis is the formation of organs from the germ layers.
Depends on the animal, but in general male produces sperm, female produces eggs, and MAY hold fertilized eggs until they grow (but not always)
The six stages of animal development are fertilization, cleavage, gastrulation, organogenesis, growth, and adulthood. Fertilization occurs when the sperm and egg fuse to form a zygote, which then undergoes cell division during cleavage. Gastrulation involves cell movements that form the three germ layers, leading to organogenesis where organs begin to develop. Finally, growth occurs as the organism matures into adulthood.

internal fertilization
Elephants are an animal that produces large piles of feces. A hippopotamus is another animal that produces large piles of feces.
Internal fertilization is essential for true terrestrial living because this means an animal will give birth to live young. Their is never any stage of development where the young depend on water to survive.
