What animal produces few eggs and what animal produces numerous eggs?
Animals that take care of their young produce fewer eggs. e.g. crocodiles. Animals that leave their young to fend for themselves produce numerous eggs. e.g. fish. This is an energy balance. You spend little energy to produce eggs, but spend more energy taking care of your offspring. Conversely, you can spend lots of energy producing many eggs and spend little energy thereafter. It's a numbers game.

Why animals that reproduce by external fertilization produce more eggs then animals that are internal?
Vertebrates that use internal fertilization tend to produce fewer eggs because almost all of their eggs are fertilized. With animals that use external fertilization, a number of eggs are never fertilized. With some animals like oysters, the males release a tremendous amount of sperm and the females release a tremendous number of eggs, but it is hit or miss if n egg will be fertilized as it floats along. A woman only needs to produce one egg to get pregnant. She can look after that baby for a few years before she gets pregnant again. just as many oysters as children are likely to survive to adulthood.
