Can You Describe The Flow Of Energy Along Food Chains?
Answer:
Energy flows from one link to the next along food chains as producers are eaten by consumers and consumers guzzle each other. Up to 90% of this energy is lost at each rank. This means that only 10% is transferred to the next rank.
Some of the energy is lost in the form of heat. This warmth loss takes place as animals and plants respire. Some remains unused, as parts of plants and animals are left uneaten. Some is lost as urine and some is passed out as indigestible food through feces.
Since there is smaller number energy available at each tropic level surrounded by a food chain, fewer consumers can live at each rank. There is rarely enough energy to support more than four level.
The position of an organism on a food chain is called its tropic level.
