Why are there usually fewer organisms at the top of an energy pyramid?

The energy pyramid has a broad base to support the next level of organisms, then gets narrower as each layer is added.
Each upper level eats more than one ie many organism from the layer below it. Therefore, there has to be more organisms and more energy trapped in lower layers to give energy to the upper layer.
There is more grass than rabbits, there are more rabbits than hawks. There is more energy in the grass layer than the layers above it.

How long does the nonoxidative energy system typically provides energy?
10-120 seconds
Why does a semiconductor have fewer electrons than a conductor?
Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
Is a statement accurate when i say that a wire carrying more electrons will transfer more energy than a wire carrying fewer electrons?
no
What organisms that make their own food for energy?
I would say a plant, i mean it does photosynthesis but does not consume anything. If not mitochondria are the parts of our cells that make energy.Supplementary answerActually although plants (green ones only) do photosynthesise compounds, they also consume stuff. That's why it's a good idea to ensure that they have fertiliser, or that the ground is fertile. And non-green plants (e.g. fungi) don't photosynthesise anyway. They need chlorophyll to be able to do that.Organisms that make their own food are plants. They are called producers. They use a process called photosynthesis. In the process, plants mix water, carbon dioxide, and sunlight, to make sugar, their food.
Why do you suppose that an energy level close to the nucleus can hold fewer electrons than one farther away from the nucleus?
it has to do with quantum numbers N,L, and M
Why are there fewer organisms higher on the energy pyramid?
The higher you are on the pyramid the less energy you get, so it takes a lot of stamina and endurance to be at the top.
Why are there usually fewer organism in the top levels of an energy pyramid?
because it shows energy transfer and how there's more energy at the bottom of the pyramid with the producer and less and less energy as the consumers eat them because they burn out that energy
Why are the numbers of organisms smaller at high levels of an energy pyramid?
The energy pyramid shows how the amount of useful energy, food, decreases as organisms in that level use it. Even though a lot of energy may be taken in at any level, more energy in the form of food that is available to the next level, is stored on the bottom level and decreases at each level as you move to the top of the pyramid. Thus, there is much less energy to support organisms at the top, so there are fewer in most communities.
Do the biomass of organisms in a typical ecological pyramid increases at each level?
The biomass of each organism decreases with each level. With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.
Can fewer organisms be supported at each level because there is less?
food/energy
Why do fewer organisms suported in each level because?
less energy and pubs
How are energy pyramids and trophic level alike?
The trophic levels show which organisms are at each level of the energy pyramid. The pyramid is shaped exactly as a pyramid. The lowest level contains the most energy and the most in number and variation of species. The next level only has 10% of the first levels' energy and fewer species. The amount of energy in the first level determines the number of levels possible. The tropical rain forest has the most levels (as many as 4) and a desert has the fewest (as few as 2).

What does a biomas pyramid represent?
I think you might be talking about a biomass pyramid. I never heard of a biotic pyramid. Take a look at this website. It might help you. http://earth.rice.edu/MTPE/bio/biosphere/topics/energy/40_biomass.html
What is the shape that has a pyramid w one fewer face than a square pyramid?
rectangular prism pyramid
Why are there fewer hawks and foxes than mice in energy pyramid?
Mice reproduce alot faster than fox and hawks, so they have a higher population.
How many fewer edges does a rectangular pyramid?
7
Why are there fewer organisms at the top of the pyramid than at the bottom?
I am in sixth grade and we are learning about this in science class right now. It's smaller at the top of the pyramid because of the populations of species; on the bottom of the pyramid, you've got abiotic elements like soil, air, water and sunlight. Since this is where the energy starts, it is at its most. Then the, let's say, grass, takes its energy (grass is a producer). Then a herbivore will eat the grass, and it will have less energy. Then carnivores will eat that herbivore, and when that carnivore dies, the scavengers will eat it's remains, which don't have much energy now. The decomposers will eat whatever the scavengers didn't and will turn it to soil. Now it is abiotic and its energy is restored. So, since there is less and less energy as you go up the pyramid, There is less and less organisms. I hope this makes sense!
