Where does the Earth get energy from? | The sun. |
How do green plants and algae use this energy? Where do they store it? | To make food during photosynthesis. They store it in the substances that make their cells. |
How else can energy disappear? | It is lost through heat energy because many animals require it to be a certain temperature (greater than their surroundings). |
How can material and energy be lost in the food chain? | Through waste materials and inedible material. |
How does this loss of energy show in biomass pyramids? | The further up you go the less energy there is because the more energy has been used up in waste and inedible materials throughout the chain. |
How else can the loss of energy explain biomass pyramids? | It explains how there are only ever maximum 5 levels in the pyramid because the excess energy is lost at each stage until there is none left. |
