Because otherwise, it wouldn't be called a "pyramid".
The producers (such as plants) at the bottom level of an energy pyramid have the most available energy. As you move up the pyramid to higher trophic levels, energy is lost through metabolic processes and heat, resulting in less energy being available to organisms at higher levels.
As the magnification of a microscope increases, the diameter of the field of view decreases. This is because higher magnification allows for more detailed observation of objects, but with a narrower field of view. Conversely, lower magnification provides a wider field of view but with less magnification.
An increase in stream velocity can be due to factors such as a steeper gradient, higher discharge, narrower channel width, or decreased channel roughness. These factors can contribute to higher flow velocities in rivers or streams.
The energy pyramid has a broad base to support the next level of organisms, then gets narrower as each layer is added. Each upper level eats more than one ie many organism from the layer below it. Therefore, there has to be more organisms and more energy trapped in lower layers to give energy to the upper layer. There is more grass than rabbits, there are more rabbits than hawks. There is more energy in the grass layer than the layers above it.
Frequency and wavelength of the sound wave change when pitch gets higher. A higher pitch corresponds to a higher frequency and shorter wavelength in a sound wave.
The lateral sides get taller and narrower. (:
A conical frustum, tat is, a cone with its apex cut off. It is usually NOT a cylinder because it gets narrower as you get higher.
An energy pyramid gets its name from its graphical shape which looks like a pyramid.
The j curve is when the population pyramid has a lot of children and few elders. So the pyramid would look like a j for example Kenya would be a good example. because it has a great amount of children and as the number gets higher the number of people gets lower.
True.
A pyramid of numbers is a graphical representation that shows the number of organisms at each trophic level in an ecosystem. To use it, start by placing the producers at the base, with the number of individuals represented as a wide bar. As you move up the pyramid to higher trophic levels, such as primary consumers and predators, the bars become narrower, reflecting the decrease in the number of organisms. This visual helps to illustrate energy flow and the balance within an ecosystem.
The field of view becomes narrower.
Because the more the food is unhealthy the higher it will be on the pyramid, but follow the new diet pyramid
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.
they had to use leverage to move the blocks higher and higher.
the rate of the operation gets higher
higher :)
