What type of diagram shows the amount of biomass available in each level in the food chain or food web?

This is called a pyramid. The base is very wide and top is very, very narrow.


What are the three types of population pyramids?

Expansive population pyramid: wide base and narrow top, indicating high birth and death rates. Constrictive population pyramid: narrow base and wider top, showing low birth and death rates. Stationary population pyramid: nearly equal widths at all age groups, suggesting stable birth and death rates.


What does a biomass pyramid measure?

A biomass pyramid measures the amount of living organic matter present at each trophic level in an ecosystem. It shows the total mass of living organisms, like plants and animals, at each level, with producers at the base having the highest biomass and top-level consumers having the lowest biomass.


The total mass of living tissue at each trophic level can be shown bY?

A pyramid of biomass or a pyramid of energy can show the total mass of living tissue at each trophic level. These pyramids illustrate the decreasing amount of biomass or energy available as you move up the food chain, with producers at the base and top-level consumers at the top.


What does a biomass pyramid present?

Biomass - the total dry weight of the organisms in a trophic levelBiomass Pyramid - a diagram showing the biomass at each trophic level of a food chainA pyramid of biomass shows energy lost in each trophic level while a pyramid of numbers shows the numbers of the organisms in each trophic level


If the height increases what happens to the lateral sides of a pyramid when you decrease the size of the base?

The lateral sides of a pyramid are going to be more steep if the size of the base is decreased. The pyramid will not be stable enough to stand on its own.


What the difference between food web and pyramid's of biomass?

A food web shows the complex network of interconnected food chains in an ecosystem, including the various paths of energy flow. On the other hand, a pyramid of biomass represents the relative amount of living organic matter present at each trophic level in an ecosystem, with producers at the base and top predators at the apex. The pyramid of biomass illustrates the quantitative differences in biomass between trophic levels, while the food web provides a more qualitative view of the interactions between different organisms in an ecosystem.


Why is the pyramid of biomass in the English channel inverted?

The pyramid of biomass in the English Channel is inverted because it reflects the high turnover rate of phytoplankton, small plants that form the base of the food chain. Phytoplankton grow rapidly and are consumed just as quickly by zooplankton and other organisms, leading to a higher biomass of consumers than producers. This inverted pyramid is common in aquatic ecosystems with fast-growing primary producers.


Why were the pyramids so strong and durable?

Pyramids have an extraordinarily wide base and an extraordinarily narrow top - this designis very stable.


Why is the pyramid widest at the bottom?

Pyramid is the name given to that particular geometric shape. If the sides were all equal length it would be called a cube .


What shape only has one base?

A pyramid (3D)! Some examples: - triangular base pyramid - square base pyramid - rectangular base pyramid - cone


When a population pyramid has a wide base and it is the most narrow at the top the population is?

When a population pyramid has a wide base and is narrower at the top, it indicates a high birth rate and high population growth. This kind of pyramid is typical of developing countries where a large proportion of the population is young and the birth rates are high.
