What is the 10% rule of ecological efficiency?
10% law. When organisms are consumed, approximately 10% of the energy in the food is fixed into their flesh and is available for next trophic level (carnivores or omnivores). When a carnivore or an omnivore in turn consumes that animal, only about 10% of energy is fixed in its flesh for the higher level.
What is the 10 rule examples?
For example, a plant will use 90% of the energy it gets from the sun for its own growth and reproduction. When it is eaten by a consumer, only 10% of its energy will go to the animal that eats it. That consumer will use 90% of that energy and only 10% will go on to the animal that eats it.
What is 10% law of energy transfer in ecosystem?
Lindemann gave the ten percent law in 1942. This law states that only 10 percent of energy in a food chain out of the total energy is transferred from one trophic level to another.
