It's a Biology question, and it means that only 10% of the energy in the trophic level before it is gained by the current consumer, the rest is lost as heat and various other by-products.
Example:
Food Chain: Sun -> Grass -> Antelope -> Lion
In this example, the grass absorbs the energy of the sun and starts the 'energy chain'. When the antelope eats the grass, it will only receive 10% of the ORIGINAL energy from the sun, the rest is given off as heat and such to the environment. When the lion eats the antelope, it will only receive 10% of the energy that the antelope received from the grass, which would then be only 1% of the ORIGINAL energy from the sun.
The other 90 percent in the 10 percent rule is lost as it gets consumed or used up as energy by the organisms in the trophic level above. This energy is used for metabolism, growth, and reproduction, and is not available to transfer to the next trophic level.
The 10 percent rule in ecology states that only about 10% of energy is transferred from one trophic level to the next in a food chain. This is because energy is lost as heat during metabolic processes, limiting the amount of energy available for organisms at higher trophic levels. Consequently, this rule helps to explain why food chains are typically limited in length.
Roughly 90% of energy is lost as you move up the energy pyramid, primarily due to metabolic processes and heat loss in each trophic level. This phenomenon is known as the 10% rule, where only about 10% of the energy consumed by one trophic level is passed on to the next.
The 10% rule in an energy pyramid is a rule of thumb that states that only about 10% of the energy from one trophic level is passed on to the next trophic level in an ecosystem. This is due to energy lost as heat during metabolism and inefficiencies in energy transfer. It helps explain why there are typically fewer top predators than producers or primary consumers in an ecosystem.
10 percent
On average, about 10% of the energy is transferred from one trophic level to the next in an ecosystem. The rest is used for metabolic processes, growth, or lost as heat. This phenomenon is known as the 10% rule.
Around 10% of the energy accumulated by plants is typically passed on to the organisms that consume them. This phenomenon is known as the 10% energy transfer rule in ecological systems. The rest of the energy is lost as heat or used for the plant's own metabolic processes.
The 10% rule is 6 CO2+ 6 H2O+ LIGHT=C6H12O6+6 O2
Energy in an ecosystem flows in whats called the 10% rule. Meaning, as you move up the pyramid 10% of energy is lost.
Ninety percent of energy is lost as heat when an organism is consumed. for example if i ate an apple with 1,000 goels of energy,I'll only get 100 goels of energy.Then if a lion were to eat me, it would only get 10 goels of energy.The rest is lost as heat energy.
answer is 1 percent b/c the insect gets 10 percent of the plant's energy, and only 10 percent of that 10 percent is available for the bird,,, free ( joey jihad ) .. youtube him
heat. Only about 10% of the energy from one trophic level is passed on to the next level, as the rest is lost as heat during metabolism. This concept is known as the 10% energy rule in ecology.
