Correct Option: D
An autotroph ("self-feeding", from the Greek autos "self" and trophe "nourishing") or "producer". Example- plants.
A heterotroph is an organism that cannot fix carbon and uses organic carbon for growth. This contrasts with autotrophs, such as plants and algae, which can use energy from sunlight (photoautotrophs) or inorganic compounds (lithoautotrophs).
Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments. These molecules can be organic (chemoorganotrophs) orinorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which utilize solar energy. Chemotrophs can be either autotrophic orheterotrophic.
Saprotroph, a term used for organisms which obtain nutrients from dead organic matt
