[Answer] 1. This poses a major threat to the leatherback sea turtle when ingested, and unfortunately one third of leatherback sea turtle adults have attempted to. What am I talking of?

Step 1 : Introduction to the question "1. This poses a major threat to the leatherback sea turtle when ingested, and unfortunately one third of leatherback sea turtle adults have attempted to. What am I talking of?"

...1. Cigarette butts 2. Food scraps 3. Cardboard 4. Plastic bags An estimated one third of adults have tried to ingest plastic, particularly plastic bags. They confuse them for their main prey - jellyfish. Some adults have been found with over five kilograms (11 pounds) of plastic inside their stomach. The plastic can block up their intestines or lead to malabsorption of nutrients. They are particularly prone to eating these closer to urban areas, especially around California, which uses up to 19 billion plastic bags a year. While I'm sure it would be dangerous for the leatherback sea turtles to digest the other options, there is no evidence that this has actually happened.

[Answer] What is the life process called in which ingested food is broken down into simple molecules which are then able to be absorbed and used by the body?

Step 1 : Introduction to the question "What is the life process called in which ingested food is broken down into simple molecules which are then able to be absorbed and used by the body?"

...You take a bite out of your apple. As you continue masticating it, chemicals in your saliva begin the digestion process. The bit of apple is broken down into smaller and smaller pieces until it reaches the state of its most basic chemical make up. As it makes its way through the stomach, more enzymes and liquids are added to the mix so that all vitamins, minerals and life-giving components are set free to be absorbed in the intestinal lining. Undigestible matter such as fiber and other waste material are eliminated at the other end. The sum of all these various processes is known as digestion.
