Which type of diagram shows the number of trophic levels an ecosystem supports?
A biomass pyramid.
What level of the food pyramid contains consumers with the least biomass?
Those at the top of the food pyramid contain consumers with the smallest number and therefore, with the least total biomass compared to the layers below them.
Why is the pyramid of biomass in the English channel inverted?
The inverted biomass pyramid is where the weight of the producers is less than the weight of the consumers. The inverted pyramid is more prevalent in aquatic ecosystems, as in such an environment, the biomass depends on the reproductive ability and the lifespan of the species. The best example is the pond ecosystem, where the mass of the producers of the ecosystem, which are generally the phytoplanktons is always less than the mass of the consumers in the ecosystem, which are generally fish and other insects.
What does a biomass pyramid measure?
Biomass. Pyramids of biomass and number are scientific models to represent all the things eaten in a foodchain. Pyramids of number are flawed as a great many insects may feed on a tree, for example, producing a narrow base to the pyramid. Pyramids of biomass are a better model as they show the dry mass of each part of the food chain and give a better indication of the energy passed between trophic layers. Biomass pyramids show the abundance of organisms at each trophic level.
Why is an ecosytem's energy pyramid wide at the base and narrow at the top?
The trophic levels are stacked in blocks, with the block representing producers forming the foundation of the pyramid. The size of the block is proportional to the biomass in each trophic level. The pyramid owes its steep shape to the loss of 90% or so of the energy with each food transfer in the chain. Found in my BIO 100 book. By Campbell Reece Simon.
What happens to the amount of biomass from the bottom to the top of the pyramid?
it decreases.
What happens to biomass as you move up its pyramid?
The Biomass decreases as the energy is used up on the way to the "top".

How would a pyramid reflecting biomass be similar to or different from an energy pyramid?
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.
What does a biomass pyramid represent?
A pyramid of biomass shows how much energy the organism on a food chain is getting from its food.
What are the concept of an ecological pyramid?
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.
What happen to biomass as you move up the biomass pyramid?
It Decreases
What happens to the biomass as you move up the biomass pyramid?
It Decreases
What happens to biomass when you move up the biomass pyramid?
It Decreases
Is biomass organic?
Biomass is the 'weight' of biological matter. often measured in a biomass pyramid.
