EVERYDAY SCIENCE

Detailed explanation-1: -An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

Detailed explanation-2: -Autotrophs. Autotrophs are organisms that use energy directly from the sun or from chemical bonds. Commonly called producers, they use energy and simple inorganic compounds to produce organic molecules.

Detailed explanation-3: -Autotrophs are organisms that produce new biomass from inorganic resources (carbon dioxide and mineral nutrients), using either light energy (photoautotrophs) or energy from reduced molecules in the environment (chemoautotrophs).

Detailed explanation-4: -A photolithoautotroph is an autotrophic organism that uses light energy, and an inorganic electron donor (e.g., H2O, H2, H2S), and CO2 as its carbon source. Examples include plants.

Detailed explanation-5: -Chemotrophs are organisms that can obtain energy from chemical substances. Chemotrophs oxidize chemical substances (both organic and inorganic compounds) and use the energy for their growth, development, and reproduction.
