What's the 10 Rule in an ecosystem


On average, only about 10 percent of energy stored as biomass in a trophic level is passed from one level to the next. This is known as the 10 percent rule and it limits the number of trophic levels an ecosystem can support.

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.
