The Biomass decreases as the energy is used up on the way to the "top".
A biomass pyramid looks like an energy pyramid, in that the largest biomass is contained in the producer level, and the least biomass is contained in the level of the highest order consumer. Basically, as you move up the energy pyramid, there is less energy available to support the biomass at each subsequent level.
Because the organisims are becoming larger
Biomass accumulates Think of it as a pyramid If the animals at the bottom consume a little then the next step up will have a little more in them because they just absorbed all of it when you get to the top you will have the highest concentration in the entire food chain.
i believe the concentration becomes greater as you move up the food chain, or up the biomass pyramid, meaning that the highest level of consumer has the highest amount of toxicity. I always thought it was the other way around but I've done some research and that's what I found.
because the biomass is getting smaller
A biomass pyramid represents the weight of food that is available in each level of a foodchain.For example, a pyramid of numbers may look like this:1 fox4 rabbits15 lettucesHowever, some things are enormous, and are eaten by many smaller animals, leading to upside down pyramids.2000 beetles1 oak treeSo, a pyramid of biomass is used to show how big everything is, making this pyramid the right way up again.1kg beetles200kg oak tree!!!!

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
