How much energy is passed from one trophic level to the next where does the rest go?
10% of the energy is passed on each trophic level. the other 90% goes out through heat.
Why is there less energy in the last consumer than first?
In each trophic level, some energy does not go to the consumer, and instead is released to the environment in the form of kinetic energy or wasted chemical energy.
Explain why an energy pyramid is used o represent the amount of energy at each trophic level?
Because a pyramid of energy distribution can be an example of numbers of organisms in a population, energy distribution, and a measure of biomass per level. The base of the pyramid or triangle is the largest, and usually represents plants and autotrophs. Because is is the largest, there are the most organisms, most energy, and most biomass. As you go higher up the pyramid or triangle, the shape gets smaller which represents the number of total organisms getting smaller, the amount of energy getting smaller and the amount of biomass getting smaller.
On the energy pyramid what level does the heterotroph go on to?
They are the consumers.
Why does radius increase if you go down a group?
Because as you go down a group, with each additional period, an additional energy level is added. Each additional energy level is farther from the nucleus than the previous energy level.
How much energy is passed from one trophic level to the next where does the rest go?
10% of the energy is passed on each trophic level. the other 90% goes out through heat.
Are biomass and trophic level related?
Each trophic level contains one-tenth as much biomass as the level below it and ten times as much biomass as the level above it.
Why is there less energy in the last consumer than first?
In each trophic level, some energy does not go to the consumer, and instead is released to the environment in the form of kinetic energy or wasted chemical energy.
What is the lowest level of the food chain?
The organism that has the least energy in the food chain is... well it depends because the ferther you go up in the tropic level the less energy you have. every time you go up you lose 10% of the energy.
What happens to the amount of energy available to each successive trophic level in a food chain?
It decreases because there are less and less animals as you go up.
What happens to the biomass of the organism as trophic levels increase?
Energy and biomass decrease as the trophic levels increase.The general rule is that only about 10% of the total energy consumed from the previous trophic level will be passed onto the next level as useable energy. As a result it takes a large biomass of producers (plants) to support the total biomass of primary consumers. The primary consumers use the energy they obtain from the plants to maintain body temperature and move or it is lost as waste. Most energy is considered to be lost as heat. This pattern is repeated for secondary consumers and so on. (This is a generality; the amount of energy transferred changes in real situations.)All life is directly related to the original energy source, in most cases the sun. The higher up you go in the trophic level, the less life (overall biomass) that can be supported by the original energy source due to the loss of energy in each level.
Why are there seldom more that five trophic levels in a food chain?
In a food chain e.g, the energy comes from the sun which reaches the grass (producer), which is eaten by the rabbit (herbivore/prey) which eats some of the energy. The fox (predator/carnivore) eats the rabbit which the fox eats the remaining energy from the rabbit, as you can see there has been energy consumed and there is not enough energy to be consumedd further.
Does a cheetah belong in a trophic level?
i hope you mean trophic levels because then my answer will be correct. and yes it would be in the top level because producers go at the bottom and since a cheetah is a top consumer (nothing else eats it) it would go at the top.
What trophic level would an autotrophic organisms occupied?
primary producer

Where do herbivores go in the trophic pyramid?
Autotrophs, being the producers in the food chain, are at the extreme bottom of the food pyramid. Then the herbivores, which are the primary consumers, follow the autotrophs. The canivores come in the next level, that is the third
What is the meant by trophic levels?
Trophic levels are the feeding position in a food chain such as primary producers, herbivore, primary carnivore, etc. Green plants form the first trophic level, the producers. Herbivores form the second trophic level, while carnivores form the third and even the fourth trophic levels. In this section we will discuss what is meant by food chains, food webs and ecological pyramids.The first trophic level is the producers, followed by the primary consumers, followed by the secondary, and finally, tertiary consumers. On the side of most energy-flow pyramids are the decomposers. I got this answer <a href="http://www.botany.uwc.ac.za/sci_ed/grade10/ecology/trophics/troph.htm">here!</a> P.S. Two people contributed. I got my answer from my science book, packets, and teacher.:)
