| Question | Answer |
| What Is Metabolic Rate? | Metabolic rate is the quantity of energy consumed by an organism per unit time |
| What Is The Word Equation For Aerobic Respiration? | Glucose + Oxygen = Carbon Dioxide + Water + Energy |
| How Can Metabolic Rate Be Measured? | Oxygen consumption, carbon dioxide, heat production and a respirometer all done over a period of time |
| What Organism Groups Have The Highest Metabolic Rate? | Birds & Mammals |
| What Organism Groups Have The Second Highest Metabolic Rate? | Reptiles & Amphibians |
| What Organism Groups Have The Lowest Metabolic Rate? | Fish |
| What Circulatory System Does A Fish Have? | A single circulatory system |
| How Many Chambers Do Fish Have? | Two (1 Atrium, 1 Ventricle) |
| How Many Times Does The Blood Pass Through The Heart? | Only Once |
| Where Is Blood Transported? | Blood is transported to the gills at high pressure to collect oxygen & return to capillaries |
| What Circulatory System Do Reptiles & Amphibians Have? | Incomplete Double |
| How Many Chambers Do Reptiles & Amphibians Have? | Reptiles & Amphibians have a three chambered heart (2 atriums & 1 ventricle) |
| Where Does The Blood Go? | Blond is returning from the lungs (Oxygenated) & the body (deoxygenated) gets mixed with the ventricle |
| What Causes The Mixing Of Blood In Reptiles & Amphibians? | Little mixing occurs due to a septum that partially divides the ventricle |
| How Do Reptiles & Amphibians Overcome The Mixing Of Blood? | They absorb oxygen through their skin |
| What Circulatory System Do Birds & Mammals Have? | Complete double |
| How Many Chambers Do Birds & Mammals Have? | Four (2 atria & 2 ventricle) |
| How Many Times Does The Blood Pass Through The Heart? | Twice |
| Where & How Is Blood Transported? | Through out the body, oxygenated blood is pumped out at high pressure increasing efficiency |
| What Does This Ensure? | This ensures a higher metabolic rates are maintained |
