Autotroph Types:
2 Types, Phototroph and Chemotroph  

There are 2 autotroph types:

(1) The type that uses photosynthesis to makes its own food.
(2) The type that uses chemosynthesis to make its own food.

Photosynthesis is a process that uses energy from light to rearrange carbon-based molecules into food.  Plants often use this process.  Therefore, plants need light to survive.

Chemosynthesis, on the other hand, uses energy from chemicals to rearrange carbon-based molecules into food.  This process does not need any light energy.  Therefore, some deep-ocean bacteria use this process in the dark, deep-sea environment.

“Rearrange carbon-based molecules into food”

Next Generation Science Standards:

HS-LS2-4  Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem..

HS-LS2-5  Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

Additional Information

Photosynthesis

A process that uses energy from light to rearrange carbon-based molecules into food.  Plants often use this process.  Therefore, plants need light to survive.

Phototroph

An autotroph that uses photosynthesis to make its own food.

Chemosynthesis

A process that uses energy from chemicals to rearrange carbon-based molecules into food.  This process does not need any light energy.  Therefore, some deep-ocean bacteria use this process in the dark, deep-sea environment.

Chemotroph

An autotroph that uses chemosynthesis to make its own food.
