The pyramid of productivity is the most widely used type of ecological pyramid, and, unlike the two other types, can never be largest at the apex and smallest at the bottom. It’s an important type of ecological pyramid because it examines the flow of energy in an ecosystem over time.
Why is biomass pyramid more accurate?
The biomass (amount of living material) of organisms in each trophic level is measured and presented in a pyramid of biomass. It is more accurate as the organism’s size is taken into account. For example, a bar representing 1 tree will be largest as it has more mass than primary consumers.
Which ecological pyramid best traces the flow of matter through an ecosystem?
Biomass pyramids show the amount of organic material at each trophic level; thus, they are the best type of ecological pyramid to use in order to model the flow of matter through an ecosystem.
What type of pyramid is considered the most representative of ecosystem structure?
All types of ecological pyramids are useful for characterizing ecosystem structure; however, in the study of energy flow through the ecosystem, pyramids of energy are the most consistent and representative models of ecosystem structure.
Why is pyramid of biomass better than number?
A pyramid of biomass is a more accurate representation of the flow of energy through a food chain than a pyramid of numbers, but seasonal variations in the rate of turnover of the organisms at a particular level may result in higher or lower values for the amount of biomass sampled at a particular time than the average …
Which pyramid is the most accurate indicator of the amount of energy available at each trophic level?
A pyramid of biomass is a more accurate indication of how much energy is passed on at each trophic level. Biomass is the mass of living material in each organism multiplied by the total number of organisms in that trophic level.
Where is the most biomass in an energy pyramid?
Explanation: In general, the higher the trophic level (increasingly apex predators), the lower the biomass. Therefore, the lowest trophic level has the greatest biomass, and those are the producers. These include things like grass, trees, and flowers.
What are the three types of ecological pyramids?
The three types of ecological pyramids include:
- Pyramid of Number.
- Pyramid of Biomass.
- Pyramid of Energy.
Which method will most accurately determine the diversity of an ecosystem?
Which of the following methods will most accurately determine the diversity of an ecosystem? Count all the species and measure their relative abundance. An ecosystem contains a certain number of species.
What does a biomass pyramid compare?
A biomass pyramid is a diagram that compares the biomass of different trophic levels within an ecosystem. It shows the mass of producers that are needed to support primary consumers, the mass of primary consumers required to support secondary consumers, and so on.
Which pyramid is most likely to be inverted?
Biomass pyramids show the relative amount of biomass at each trophic level. Biomass is the mass of living things in a particular trophic level. Most pyramids are larger at the bottom, but marine biomass pyramids are often inverted. This is because the producers are very small and have limited mass.
Which is the most stable ecosystem?
The correct answer is Ocean. The ocean is the most stable ecosystem: It is stable due to its natural liquid nature (saline), dissolved oxygen, light, and temperature. An environment is considered to be stable when its structure and function remain unchanged for a long period of time.
Which ecological pyramid is most representative of functional characteristics of an ecosystem?

Where is the most biomass found in an ecosystem?
For animals, most biomass is concentrated in the marine environment, and for bacteria and archaea, most biomass is concentrated in deep subsurface environments.
What species has the largest biomass on Earth?
Antarctic krill form one of the largest biomasses of any individual animal species.
Which pyramid is both inverted and upright?
The pyramid of biomass can be both upright and inverted.
