Waste.
Or there might be more specific answers but for a middle school or lower high school that would be a good answer.
Waste materials that the body cannot use are typically eliminated through urine, feces, sweat, or respiration. These waste materials are processed and filtered by the kidneys, liver, and other organs before being excreted from the body.
Materials that the body cannot use are often excreted as waste products. These may include excess minerals, toxins, or certain molecules that are not metabolically useful for the body's functions. The kidneys and liver play important roles in filtering out and removing these unusable materials from the body.
Absorbtion takes place in the stomach and intestines. Much of absorption takes place in the small intestines. When materials in the body are not absorbed the body gets rid of them. They are excreted as sweat, urine and stool.
The process of breaking down food to its building blocks is called digestion. We can then absorb the products and use them in our bodies.
Materials like glass, plastic, and metals such as stainless steel and aluminum are typically non-porous and therefore cannot absorb water. This makes them ideal for use in applications where water absorption is a concern, such as food containers or waterproof coatings.

no; doing so only gets rid of the food materials that the body cannot make use of once all of the energy has been absorbed into the body
Digesting. It's the closest answer!
Materials people use from the earth are called natural resources.

Osmosis
"circulatory"
You cannot use just weight to identify a material.You can use density to identify materials.
Due to the current population figures and projections, we cannot continue to use and dispose of materials or we will be living in our neighbor's garbage. The use of non-biodegradable materials must be severely restricted.
