Is a biomass pyramid more stable with a wide base or a narrow base?

A biomass pyramid is more stable with a wide base because it indicates a greater amount of primary producers, such as plants, which provide the foundational energy and nutrients for the entire ecosystem. A wide base allows for a larger biomass at lower trophic levels, supporting a diverse range of organisms at higher levels. In contrast, a narrow base suggests fewer producers, leading to instability and vulnerability in the ecosystem due to limited energy availability.


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.


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 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.


Why is an energy pyramid wide at the bottom and narrow at the top?

An energy pyramid is wide at the bottom because it represents the large amount of energy available at the producer level. As you move up the pyramid to higher trophic levels, less energy is available because energy is lost as heat through respiration and metabolism, resulting in less energy being transferred to each successive level. This explains why the pyramid narrows towards the top.


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.


How wide is the base of the great pyramid?

The length of each side at the base is 755.55 feet or 230 meters


What is the similarity between a cone and a pyramid?

They both ave a wide base and come to a point.


What is the opposite of narrow?

The opposed of narrow is wide.


What do laborers built around the entire base of pyramid?

Laborers built a wide bank of rubble around the base of the pyramid to serve as a foundation. This bank was then faced with fine Tura limestone.


Where does sea kelp fit on the energy pyramid?

At the wide part in the bottom. They are primary producers


Do waves that are narrow have lots of energy?

No, waves that are narrow typically have less energy compared to waves that are wide. The energy of a wave is determined by its amplitude and frequency, with narrower waves usually having lower amplitudes and frequencies.
