Less kilo calories being transfered as the trophic level rises

Someone is on Chapter 2 Section 2: Flow of Energy in an Ecosystem problem 15. EXPLAIN why an ecological pyramid is smaller at the top than at the bottom.
Bottom, ProducerTop, Tertiary/ Carnivores
All pyramids are smaller at the top. It's how they're constructed. Every step of energy transformation has loss. Progress through the energy chain, the amount of energy transferred would unavoidably degrade. As the chain progresses, it gets narrower to a pyramid shape.
I'd say because most things at the top are less hunted organisms, leaving it to be eaten less. Which will result in a smaller amount.Rather than the rest of organisms, there are more and larger because they are the hunted.Because of energy the bottom gets 100% of the energy the next only gets 10% then 1% then .1% and so on.An ecological pyramid is a diagram that shows the relative amounts of energy or matter contained within each trophic.
It is in the shape of a pyramid to show at the bottom it is big which gives 10% and then it gives off smaller and then smaller amounts of energy to make the point at the top.
It is in the shape of a pyramid to show at the bottom it is big which gives 10% and then it gives off smaller and then smaller amounts of energy to make the point at the top.
The ecological pyramid is basically the food chain. So, the producers (plants) are at the bottom, then herbivores (plant eaters), then above them are the omnivores or carnivores, and then the most powerful and top of the food chain animals are at the top of the pyramid.
No, it isn't. The bigger the denominator (bottom number), the smaller the fraction ~x
A pyramid is bigger at the bottom and small and pointy at the top. so its bigger at the bottom, otherwise it would have been called an energy upside-down pyramid =). But anyway, energy enters a food chain from the sun. some energy and biomass is lost at each stage of a food chain as feaces, movement energy and heat energy (especiall birds and mammals). therefore only a small amount of energy and biomass is incorporated into a consumer's body and transferred to the next feeding level. the loss of energy and biomass at each stage is a representation of why the pyramid gets smaller at the top.
the slaves
This is because only 10% of the energy is transferred from one trophic level to another so relatively less no of herbivores can survive on a number of plants and so on. hence with respect to mass, energy or number, the thickness of the pyramids decreases from bottom to the top.
