View Full Document. Organisms that can't make their own food and have to get their energy by consuming other organisms are called heterotrophs . Energy can be converted from one form to another and can be transferred from one organism to another. Most of the energy comes directly or indirectly from the sun.
The energy is used by the organism to carry out metabolic activity (all the things that cells do to keep you alive). The definition of a food chain is the transfer of energy from one organism to another. The arrows point to the organism that receives the energy. These arrows are called strands. Producers are organisms that make their own food. Some, but not all, organisms make their own food using a process called photosynthesis. They use the sun's energy to combine carbon dioxide (CO2) and water into a food called glucose. Plants, algae and some types of bacteria (cyanobacteria) produce their own food this way. Producers also include certain types of bacteria that use chemical energy (instead of the sun) to make their own food.
