Why is pyramid a good shape to represent how matter and energy transfer in an ecosystem?

23) Why is a pyramid a good shape to represent how matter and energy transfer in an ecosystem? … Producers because they directly control the numbers of other organisms in the ecosystem. The food in an ecosystem (wether the producers or the prey) directly control the numbers of the trophic level above them.

Why is a pyramid a good shape to use to represent energy in an ecosystem?

B is correct. An energy pyramid shows the flow of energy at each trophic level in an ecosystem. A pyramid shape is used because energy is lost at each trophic level when organisms use it up.

Do you think pyramid is a good shape to represent how matter and energy transfer in an ecosystem?

5. Do you think a pyramid is a good shape to represent how matter and energy transfer in an ecosystem? Why or why not? Answers will vary but acceptable answers include that pyramids are a good way to represent that only a fraction of the energy from a lower trophic level passes up to each higher level.

Why is a pyramid a good shape in a food chain?

The reason for the pyramid shape is simple. There must always be enough plants producing food at the bottom, or else the whole food chain would collapse. Higher up, no predator (consumer) can be as common as its prey, otherwise both animals would soon die out.

Why is the energy pyramid important?

An energy pyramid is useful in quantifying the transfer of energy from one organism to another along a food chain. Energy is higher at the bottom of the pyramid, but it decreases as you move up through the trophic levels.

Why is a trophic pyramid energy pyramid an effective model for quantifying energy flow?

It suggests that for any food chain, the primary producer trophic level has the most energy and the top trophic level has the least. 8. Why is a pyramid an effective model for quantifying energy flow? The pyramid shape shows a hierarchy but also relative amounts at each level.

What makes an energy pyramid different than a food web or chain?

Explanation: Food chain refers to the chain of consumption of the organisms in the ecosystem and the overall contribution of this consumption to the ecosystem. … However, the energy pyramid considers the energy transfer as one organism eats another.

Do organisms use 90% of the available energy at each trophic level?

Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).

Why are pyramids of biomass useful?

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. … Pyramids of biomass are used to overcome the problem of inverted pyramids of number.

How does a pyramid of numbers relate to a food chain?

A pyramid of numbers shows the population at each stage in a food chain . It is drawn as a bar chart with the bars stacked on top of each other. The wider the bar, the more organisms it represents. The producer always goes at the bottom of the pyramid.

Why is a pyramid shape used to show the trophic levels?

Describe why the pyramid shape is used to represent energy, biomass, and numbers pyramids. The pyramid is used because it can represent energy available at every trophic level, and at each level everything gets smaller as you go up the pyramid.
