Autotroph
* All autotrophs are primary producers
  - require sunlight to produce carbohydrates
* Most autotrophs are green plants, algae, and some bacteria
  - break down carbohydrates
  - make food
* Most autotrophs use a process called photosynthesis to make their food
  - the process of photosynthesis to produce theie food
  - utilize sunlight
* Some autotrophs obtain energy.
* Some autotrophs produce food
  - use light
* absorb sunlight energy and transfer inorganic mineral nutrients into organic molecules.
* also are referred to as primary producers
  - give out oxygen which is vital to the survival of humans
* are at the base of food webs
  - considered producers in a food chain
  - critical for all ecosystems
  - eaten by herbivore s, organisms that consume plants
  - needed in every food chain in all ecosystems
  - of two types, chernosynthetic and pholosynlhetic
* are organisms like plants that make their own food
  - that are able to make their own food using carbon dioxide
* are organisms that can make their own food
  - produce their own food
  - use inorganic compounds to make organic nutrients
  - make their own food through either chemosynthesis or photosynthesis
  - manufacture their own food
  - obtain their carbon atoms from carbon dioxide
  - producers and synthesize their own carbon source for food
  - producers, green plants that convert light energy into food that can be consumed
  - self-feeders
* are the base of the food chain
  - unit of all stored energy in any ecosystem
  - green plant which contains chlorophyll
* are the producers in a food chain, such as plants on land or algae in water
* are the producers of the biosphere
  - typically non-motile and heterotrophs are typically motile
  - usually plant s or one-celled organisms
  - vegetation
* can fix carbon dioxide and turn it into organic molecules
  - go on hunger strikes for years and even decades
  - grow using simple, inorganic chemicals
  - reduce carbon dioxide to make organic compounds, creating a store of chemical energy
  - revert to being heterotrophs if no light energy
* capture solar energy and convert it to chemical energy.
* fix carbon dioxide to make their own food source
  - the released carbon dioxide once again, release new oxygen, and the cycle continues
* form the base of the energy pyramid.
* includes cell membranes
  - cells
  - corpi
  - cytoplasm
  - nuclei
  - plant parts
  - plasma membranes
  - sections
  - vacuoles
* make all their own compounds starting with carbon dioxide, ammonia, and water
* manufacture their own energy by photosynthesis or chemosynthesis.
* obtain the required energy to create their own food directly from the sun.
* produce their own food from simple raw materials
  - sugars, lipids, and amino acids
* synthesize organic materials from inorganic materials.
* take it from solar radiation and heterotrophs take it from autotrophs.
* use energy from the sun to produce their own materials for growth etc
  - light energy directly while heterotrophs benefit from light energy indirectly
  - the food they make to carry out their own life functions

### plant | autotroph:

Chemosynthetic autotroph
* are a necessary part of the nitrogen cycle.
* make their food by breaking down sulfur and nitrogen.

Photosynthetic autotroph
* Most photosynthetic autotrophs make food.
* Some photosynthetic autotrophs use compounds other than carbon dioxide or water.
* require four main ingredients to produce carbohydrates.

Autotrophic organism
* are often primary producers in their ecosystems
  - producers that generate organic compounds from inorganic material
* can use all three forms.
* create their own food.
* require an energy source to synthesize organic molecules.
