autotrophs are organisms that make their own food . they take in energy from the sun and make carbohydrates through the process of photosynthesis...
A primary consumer (heterotroph). For example, any herbivore.
The size of a molecule may affect the way in which an organism obtains the nutrients because the larger the molecule you have, the more the element can hold, so that would mean that there would be more nutrients for the organism.
An autotroph is a plant, which makes it's own energy. A heterotroph is an animal that eats other organisms to get energy.
Obtain energy by breaking down organic molecules. Heterotrophs are unable to synthesize organic carbon-based compounds independently from the inorganic environment's sources (e.g. Animalia, unlike Plantae, cannot photosynthesize) and therefore must obtain their nutrition from another heterotroph or an autotroph.

Most autotophs that live in environments that have no light rely on chemosynthesis to synthesize energy storing molecules (mostly as carbohydrates). Many chemosynthesizers live near hyrdrotermal vents and use the hydrogensulfide emitted by the vents to "fuel" the chemical processes of chemosynthesis.
Detritus
It's a heterotroph.
Heterotrophs. For example: fish and frogs.
saprobiotic organisms. many are bacteria or fungi
The heterotrophs obtain food energy and other nutrients from autotrophs.
No. An autotroph (auto = self; troph = nutrition) is an organism that obtains the energy it needs to live and grow via energy from the sun (photoautotrophy) or energy stored in the chemical bonds of simple inorganic molecules (chemoautotrophy). An owl is regarded as a heterotroph (hetero = other) because it obtains the energy it needs to live and grow by consuming other living organisms, such as rodents.
A Shark obtains nutrients by eating.
autotroph, because it creates energy by itself from basic parts, using sun energy and CO2.
Inorganic substances
An autotroph is an organism that only needs inorganic nutrients and sunlight to survive. (eg. plants)
An animal or plant that obtains nutrients from animals is a carnivore.
It obtains nutrients from its environment
