Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments. These molecules can be organic or inorganic. The chemotroph designation is in contrast to phototrophs, which utilize solar energy. Chemotrophs can be either autotrophic or heterotrophic. Chemotrophs are commonly found in ocean floors where sunlight cannot reach them because they are not dependent on solar energy. Ocean floors often contain underwater volcanos that can provide heat to substitut
Answer 1: A heterotroph is any living organism that obtains its energy from carbohydrates and other organic material. In simpler terms, heterotrophs are organisms that cannot produce their own food, therefore they eat other organisms that CAN produce their own food.All animals and most bacteria and fungi are heterotrophic. Heterotroph is a living organism that obtains its energy from carbohydrates and other organic material. All animals and most bacteria and fungi are heterotrophic. i.e. people and animals eat complex carbohydrates and sugars which they metabolize to produce energy.
