Matter and Energy in Ecosystems Vocabulary 1) Producers- an organism which produces food through photosynthesis, and certain bacteria that are capable of converting inorganic substances into food through chemosynthesis. 2) Consumers- an organism that gains energy by eating other organisms. 3) Fossil fuels- A hydrocarbon deposit, such as petroleum, coal, or natural gas, derived from the accumulated remains of ancient plants and animals. 4) Aerobic- the production of energy from glucose metabolism that requires the presence of oxygen. 5) Anaerobic- the production of energy occurring in the absence of oxygen or not requiring oxygen to live.
