Final answer:

Phosphorus is a non-metal that is vital for forming DNA, phospholipids, and the bony structures in animals, and it is present in tissues such as muscles and the liver.

Step-by-step explanation:

The non-metal that is an essential component of DNA and various animal tissues and bones is phosphorus (a). Phosphorus is crucial in living processes and is a major constituent of nucleic acids, phospholipids, and, as calcium phosphate, it forms the supportive components of our bones. It is present in all body cells, including those in tissues such as muscles and the liver. Calcium, magnesium, and phosphorus are constituents of bone and teeth. Phosphorus is also considered a limiting nutrient in many aquatic ecosystems, necessary for growth.
