Veal had an orrery, an electrifying machine, a turning lathe, a theatre (in the wash-house), a chemical apparatus, and what he called a select library of all the works of the best authors of ancient and modern times and languages.
The main difference between autotrophic and heterotophic cells is  that autotroph cells produce their own food, while heterotrophic  cells do not. Another difference is that â¦ autotrophs obtain carbon  from inorganic sources like carbon dioxide, while heterotrophs get  their reduced carbon from other organisms.
This contrasts with autotrophs, such as plants, algae and  some bacteria, that can use energy from sunlight (photosynthesis)  or inorganic compounds to produce organic compounds such as  carbohydrates, fats, and proteins from inorganic carbon dioxide.   Humans are a good example of heterotrophs.That's why we eat a lot  of plants.   A heterotroph is any organism that requires organic subtrates in  order to survive.    Basically, a heterotroph is a consumer which must eat other animals  and cannot produce its own food. It is referring to the consumers in the food chain, such as  animals,fungi and many bacteria. More scientifically, it's the life  form that uses organic carbon for growth. This contrasts with  autotrophs, which are the producers, mainly plants, in the food  chain.
