Here are the essential concepts you must grasp in order to answer the question correctly.
Nutritional Composition of Egg Yolk
Egg yolks are rich in fats, proteins, and cholesterol, which are essential nutrients for the developing embryo. The high fat content provides a concentrated source of energy, while proteins are crucial for growth and development. Cholesterol plays a vital role in cell membrane formation and is a precursor for steroid hormones.

Embryonic Development
During embryonic development, a chick requires a significant amount of energy and building blocks to form tissues and organs. The nutrients in the egg yolk support rapid cell division and differentiation, ensuring that the embryo can develop properly until it is ready to hatch.

Evolutionary Adaptation
The high nutrient density of egg yolks is an evolutionary adaptation that enhances the survival of avian species. By providing a rich source of energy and nutrients in a compact form, egg yolks ensure that the developing chick has everything it needs to thrive in the early stages of life, increasing the likelihood of successful reproduction.
