The body cannot manufacture the following substances that food provides - vitamins minerals proteins fat carbohydrate water
minerals cannot form from materials that were once part of a living thing. for example a crystal that falls out of a tree or is made by a tree is not inorganic so it doesn't count as a mineral
Cleavage is a plane of atomic weakness in an inorganic mineral. Since pearls are an organic gem, they cannot have cleavage. The fracture surface of a pearl can be described as conchoidal.
An element cannot be separated into simpler substances by chemical means.
All substances can be broken into any other substances (or elements) by chemical or physical methods.
As far as I'm aware the molecules of all vitamins contain carbon atoms, so they are all 'organic' in the chemical sense of the term.

An autotroph is an organism that can create nutritional substances from simple inorganic substances, like a plant that undergoes photosynthesis. As a whale cannot do this, no, they are not autotrophs, they are heterotrophs.
Minerals do not nor cannot live nor die because they are inorganic materials, or materials that do not come from living organisms.

Rocks are solid substainces that are made of 2 or more minerals and can have organic matter in them as well. On the other hand, minerals are naturally formed inorganic solids that have definite crystalline structures. Rocks and minerals are made through different processes.
animals need oxygen and plants produce oxygen. if there is no light for photosynthesis, then plants can not produce oxygen and animals cannot survive
because it is carbon containing compound
Elements.
An element cannot be separated into simpler substances by chemical means.
