Only a few animals are at the top of an energy pyramid because they are apex predators, which typically have fewer individuals in a food chain due to the decrease in available energy as it moves up the pyramid. The energy available at each level limits the number of individuals that can be supported as it is passed up the food chain.
In a stable ecoystem, there should always be more producers than carnivores. For one, there has to be more energy, because your energy flow has to reach the top of the pyramid through your primary, secondary, etc. consumers. There has to be more at the bottom because the organisms at the upper levels have to have a food source. How would the jungle look if there were 100 tigers and only 1 plant?
There are few organisms at the top of an energy pyramid because energy is lost as it moves up the food chain through each trophic level. The top predators have less available energy because much of it has been used by the organisms at lower trophic levels for their own metabolism and growth. This limits the number of organisms that can be supported at the top of the energy pyramid.
The 10 percent rule states that only about 10 percent of energy is transferred from one trophic level to the next in an ecosystem, resulting in a smaller biomass available at higher trophic levels. This is reflected in the biomass pyramid, where each successive trophic level has less biomass than the level below it due to energy loss through respiration, heat, and waste.
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
An energy pyramid is like a food chain, because at the top of the pyramid, there is the most energy, and at the bottom there is the least energy. The same goes for a food chain, because the producer has 100% of the energy. The final consumer, or tursury consumer, has either little or no energy left from the primary, and secondary consumers, because they have used up almost all the energy breathing, moving and during digestion.

If the organisms in a food chain are arranged according to trophic levels, they form a pyramid, with a broad base representing the primary producers and usually only a few individuals in the highest part of the pyramid. Also known as a "pyramid of numbers," an ecological pyramid is a way of describing the distribution of energy, biomass, or individuals among the different levels of ecosystem structure.
Only about 10% is passed from level to level. In this case it is 10% of 1500 calories or 150 calories. This the reason why there has to be many, many producers and why there are only a few consumers. And why you will only see a few eagles or wolves at the very top of the pyramid.

timbuktu
yes but only a few kinds
because there is not that many animals that eat other animals.
