Detailed explanation-1: -Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.

Detailed explanation-2: -Autotrophs obtain energy and nutrients by harnessing sunlight through photosynthesis (photoautotrophs) or, more rarely, obtain chemical energy through oxidation (chemoautotrophs) to make organic substances from inorganic ones.

Detailed explanation-3: -Autotrophs are organisms that undergo autotrophic mode of nutrition. These are the organisms that can prepare their own food from simple substances like carbon dioxide and water. All green plants are examples of autotrophs.

Detailed explanation-4: -An autotroph is an organism that can make its own food by synthesizing organic nutrients from inorganic materials, using energy from sunlight or a chemical source to drive the process. The word autotroph comes from the Greek words auto, meaning “self, ” and troph, meaning “feeding.”
