Question | Answer |
Sun | The source of almost all energy used by living organisms |
Producers | organisms that produce their own food |
Consumers | organisms that eat living producers and/or other consumers for food |
Herbivore | a consumer that eats producers exclusively (only) |
Carnivore | a consumer that eats only other consumers |
Omnivore | a consumer that eats both producers and consumers |
basal metabolic rate | the minimum amount of energy required by the body in a day |
combustion reaction | the chemical process by which organisms get energy from food |
Monosaccharides | simple carbohydrates (simple sugars) |
Disaccharide | formed when two monosaccharides link up |
Polysaccharide | formed when several monosaccharides link up (such as a starch) |
Calorie | a unit used to measure energy from the food your body uses |
Oxygen | Combustion requires this gas |
Energy, CO2 and water | The products of combustion |
Macronutrients | What carbohydrates, fats and proteins are called, collectively |
Amino acids | Protein is made up of these building blocks |
Endothermic | The scientific word for warm-blooded |
Ectothermic | The scientific word for cold-blooded |
Glycolysis | The first step in combustion in living organisms does not require oxygen and is where glucose is broken into two parts |
Krebs cycle | Two parts of glucose are used to produce energy, CO2 and hydrogen in the presence of oxygen |
Electron transport system | This part of combustion in living organisms releases the most energy |
Mitochondria | The powerhouse of the cell where the Krebs cycle and the Electron Transport System is completed |
