Dude are you kidding me dumb
Energy pyramid
A biomass pyramid.
The trophic levels show which organisms are at each level of the energy pyramid. The pyramid is shaped exactly as a pyramid. The lowest level contains the most energy and the most in number and variation of species. The next level only has 10% of the first levels' energy and fewer species. The amount of energy in the first level determines the number of levels possible. The tropical rain forest has the most levels (as many as 4) and a desert has the fewest (as few as 2).

The major types of ecological pyramids are a pyramid of numbers or biomass or energy.The pyramid of numbers depicts the number of individual organisms at different trophic levels of food chain. Successive links of trophic structure decrease rapidly in number until there are very few carnivores at the top.In many ecological pyramids, the producers form the base and the successive trophic levels make up the apex. The apex is a term meaning pointed top.Energy pyramids are always slopping because less energy is transferred from each level than was paid into it.
The diagram that shows trophic levels on blocks is called a pyramid of energy or ecological pyramid. It visually represents the flow of energy through different trophic levels in an ecosystem, with each block indicating the amount of energy available at each level. Typically, producers (plants) are at the base of the pyramid, followed by herbivores, then primary and secondary carnivores at higher levels.

An ecological pyramid is a graphical representation of the trophic (feeding) relationships within an ecosystem. It shows the transfer of energy and matter between trophic levels, meaning that energy decreases as you move up the pyramid. There are three types of ecological pyramids: pyramid of numbers, pyramid of biomass, and pyramid of energy.
A number pyramid in an ecosystem illustrates the relative abundance of different trophic levels within the food chain. It shows that the number of individuals decreases as you move up the pyramid due to energy loss from one trophic level to the next. This helps us understand the structure and dynamics of energy flow within the ecosystem.
The first of the four, is the ecological pyramid. It shows the number of organisms in each of the trophic levels in an ecosystem. At the base of the levels are the producers and at the top of the pyramid are the final consumers. The second is the number pyramid. This also shows the number of organisms in each of the trophic levels but it does not take into consideration the size of each of the organism in the levels. This pyramid has four levels, starting from the bottom is the total number of producers, then the total number of herbivores, third the total number of small carnivores, and finally the total number of large carnivores. The third pyramid is the biomass pyramid. This pyramid is an indication of the total mass of organisms in the trophic levels. There are three levels of biomass in this pyramid. These are producers ( 470.0 g/m2), then herbivores (0.6 g/m2), and last the carnivores ( 0.1 g/m2). And it is possible for the second level to be greater than the third. Last, is the energy pyramid which indicates the total amount of energy that is in the trophic levels. It also is able to show the loss of energy between the trophic levels. The four levels in this pyramid are Producers, Primary consumers, Secondary consumers and at the top are the Tertiary consumers. As energy passes between the levels, such as from producers to primary consumers, much of the energy is lost due to waste and the conversion to heat energy.
