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.
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.
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.
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.
True.
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.
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
they had to use leverage to move the blocks higher and higher.
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.
the rate of the operation gets higher
higher :)
There are fewer organisms higher on the energy pyramid because energy is lost as it moves up the food chain through consumption and metabolism. This results in less energy available to support higher trophic levels, leading to a decrease in the number of organisms at each successive higher level.
