# Quick Answer: What Happened To The Lost Energy?

## Which trophic level has the least amount of energy?

It follows that the carnivores (secondary consumers) that feed on herbivores and detritivores and those that eat other carnivores (tertiary consumers) have the lowest amount of energy available to them..

## Can light be destroyed?

YES, light can be destroyed , but its energy cannot be destroyed . when the energy in the light changes to another form(like heat)..you can say that light is destroyed. … If you meant destroying energy that photons possess, no you can’t destroy it. In the above example the energy is just converted into heating water.

## Can kinetic energy be lost?

An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. … This type of collision is perfectly inelastic because the maximum possible kinetic energy has been lost.

## What is the equation for energy lost?

The kinetic energy the person has upon reaching the floor is the amount of potential energy lost by falling through height h: KE = −ΔPEg = −mgh.

## Why does the 10% rule exist?

The 10% Rule means that when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on. An energy pyramid shows the feeding levels of organisms in an ecosystem and gives a visual representation of energy loss at each level.

## What is the 10% rule?

The 10% rule states that between one trophic level to the next only 10% of the energy is passed on to the next. So if producers have 10,000 J of energy stored through photosynthesis, then only 1000 J is passed on to primary consumers.

## Why is only 10 percent of energy passed on?

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

## Can you destroy energy?

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. … In other words, energy cannot be created or destroyed.

## Is energy ever lost?

No, the law of conservation of energy states that energy cannot be destroyed (lost) or created – it can only change from one state of energy to another. … It is a fundamental Law of Physics that energy is never lost, nor destroyed.

## How do you find energy lost to heat?

To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change in …

## Why is some energy always lost as heat?

The second law of thermodynamics explains that it is impossible to have a cyclic (repeating) process that converts heat completely into work. … Some amount of energy in a reaction is always lost to heat. Also, a system can not convert all of its energy to working energy.

## What causes human energy loss?

Lack of energy can be a normal response to inadequate sleep, overexertion, overworking, stress, lack of exercise, or boredom. When part of a normal response, lack of energy often resolves with rest, adequate sleep, stress management, and good nutrition.

## Is energy lost when it changes form?

When energy changes forms, energy is conserved. What does this mean? It means that no energy is lost. That does not mean all the energy that changes form goes where we want it.

## Why does a ball not bounce back to its original height?

This elastic potential energy is why the ball is able to bounce, or rebound. After the ball rebounds, the elastic potential energy is transformed into kinetic energy, but it will never possess as much kinetic energy as during its original fall. The ball will never be able to rebound to its original height.

## Why is energy lost?

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. … A food chain can usually sustain no more than six energy transfers before all the energy is used up.

## What happens to the other 90% in the 10% rule?

Ten Percent Rule: What happens to the other 90% of energy not stored in the consumer’s body? Most of the energy that isn’t stored is lost as heat or is used up by the body as it processes the organism that was eaten.

## Why is energy 90 lost?

The rest of the energy is passed on as food to the next level of the food chain. The figure at the left shows energy flow in a simple food chain. Notice that at each level of the food chain, about 90% of the energy is lost in the form of heat. … Therefore, as you move up the food chain, there is less energy available.

## Which level has the most energy?

Since the source of energy is the sun, the trophic level representing producers (plants) contains the most energy.

## How do animals lose energy to the environment?

Energy is lost due to: The whole organism not being eaten (skeleton and fur left behind). Not all the food being digested – some passes out of the animal in excretion or egestion . Energy being lost as heat in respiration and therefore not being passed onto the next level.

## Are humans just energy?

In life, the human body comprises matter and energy. That energy is both electrical (impulses and signals) and chemical (reactions). … Remarkably, at any given moment, roughly 20 watts of energy course through your body — enough to power a light bulb — and this energy is acquired in a plethora of ways.

## Where does the lost energy go?

While the total energy of a system is always conserved, the kinetic energy carried by the moving objects is not always conserved. In an inelastic collision, energy is lost to the environment, transferred into other forms such as heat.
