- Energy and Biomass
- All living organism are interdependent which means they depend on each other in order to survive and reproduce.
- Energy from the Sun is the source of energy for nearly all living organisms on the Earth.
- Plants convert a percentage of the light energy into glucose.
- The rabbit then eats the plants and uses up energy from the plant whereas the rest of it is stored in its body.
- The fox eats the rabbit and gets some energy stored in its body.
- The rabbit then eats the plants and uses up energy from the plant whereas the rest of it is stored in its body.
- Plants convert a percentage of the light energy into glucose.
- Energy is used up at each stage in the food chain to stay alive i.e. respiration. A lot of energy is lost to the surroundings as heat. Material and energy are also lost from the food chain in droppings.
- You hardly ever get food chains with more than 4 or 5 trophic levels because so much energy is lost at each stage that there is not enough to support more organisms.
- Biomass is the weight of the creatures at each level of a food chain if you were to put them together.
- This biomass is a store of energy so a pyramid of biomass shows how much energy there is at each stage in the food chain.
- The fox eats the rabbit and gets some energy stored in its body.
