Why do organisms that fertilize internally tend to produce fewer eggs than those that fertilize externally?

Organisms that fertilize internally often invest more resources in each egg and the resulting offspring, as they provide a more controlled environment for development. This strategy allows for higher survival rates of the young, leading to fewer eggs being produced. In contrast, external fertilization typically involves a larger quantity of eggs to increase the chances of survival amidst greater predation and environmental risks, as the fertilized eggs are often more vulnerable. Thus, the reproductive strategies of these organisms reflect their differing environments and survival tactics.
