Consumers | | | and decomposers are heterotrophs. | +-----------------------------------+-----------------------------------+ | Autotroph | An organism that is a | | | self-feeder. An autotroph is a | | | producer. | +-----------------------------------+-----------------------------------+ | Trophic level | An energy or feeding level | | | (producer→primary | | | consumer→secondary | | | consumer→tertiary consumer) | +-----------------------------------+-----------------------------------+ | Energy | The ability to do work or cause | | | change | +-----------------------------------+-----------------------------------+ | Producer | An organism that uses | | | photosynthesis to make its own | | | food | +-----------------------------------+-----------------------------------+ | Consumer | An organism that gets energy by | | | eating other organisms | +-----------------------------------+-----------------------------------+ | Decomposer | An organism that breaks down dead | | | or decaying consumers and | | | producers via chemical reactions | | | and uses the energy released from | | | rearranging those molecules for | | | growth and development. | +-----------------------------------+-----------------------------------+ | Photosynthesis | The process that converts the | | | Sun\'s energy into food | | | (glucose). | +-----------------------------------+-----------------------------------+ | Cellular Respiration | The process that takes the | | | incoming food into a cell and | | | turns it into energy the cell can | | | use (ATP). | +-----------------------------------+-----------------------------------+ Key Concepts 1. 2.
