Detailed explanation-1: -Organisms that synthesize food molecules through photosynthesis are referred to as photoautotrophs whereas those that do so through chemosynthesis are called chemoautotrophs. Another name for an autotroph is autophyte. It can also be called a producer for its capacity to produce its own food.

Detailed explanation-2: -synonyms: autophyte, autophytic plant, autotrophic organism, producer.

Detailed explanation-3: -Autotrophs are called producers as they make food required by all other organisms. Heterotrophs are called consumers as they consume food prepared by autotrophs.

Detailed explanation-4: -Autotrophs or primary producers are organisms that acquire their energy from sunlight and materials from nonliving sources. Algae, higher plants, and some bacteria and protists are important autotrophs in running waters. Heterotrophs obtain energy and materials by consuming living or dead organic matter.
