What happens to the number of organisms as you move from the bottom of an energy pyramid to the top?
The number of higher-level consumers (higher in the pyramid) usually decreases, as they typically consume more than one prey.
How are energy pyramids and trophic level alike?
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).

Which type of diagram shows the number of trophic levels an ecosystem supports?
A biomass pyramid.
What three things are ecological pyramids used to represent?
An ecological pyramid was a concept developed by Charles Elton. It is a graphical representation designed to show the number of organisms, biomass of an ecosystem and energy relationships.
What does each type of ecological pyramid depict?
An ecological pyramid is simply a graphical representation of the relationship at each trophic level in a particular ecosystem. There are three types of ecological pyramids: of numbers, of energy, and of biomass. For example the pyramid of numbers is a representation of the number of organisms in each trophic level, with herbivores at the bottom as primary consumers, followed by first level carnivores and so on.
Where on the energy pyramid will you find the highest number of organisms?
phospholipids
Energy pyramid Fox Grasshoppers Birds Grass Which has the smallest numbere of organisms?
In the context of an energy pyramid, between foxes, grasshoppers, birds, and grass, foxes have the smallest number of organisms. There are 21 species of foxes.

What are the 4 kinds of ecological pyramind?
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.
What is the advantage of using a biomass or energy pyramid rather than a pyramid of numbers?
Not all organisms have the same mass. Consider 1 whale versus 5,000 plankton - the whale has much greater mass, but only 0.1% of the total number of organisms. When you compare mass, you get a better idea of how much energy is actually available at that trophic level. Basically, they are better to understand.
Which type of diagram shows the number of trophic levels an ecosystem supports?
A biomass pyramid.
What does a number pyramid tell you about an ecosystem?
Shows the relative number of individual organisms at each trophic level.
What does it mean if an ecosystem is balanced?
- The organisms have to fit into the energy pyramid- The largest number of organism in any ecosystem needs to be the producers- The smallest number of organism need to be the highest level of consumers in that ecosystem
Why are there usually few organisms at the energy pyramid?
In a stable ecoystem, there should always be more producers than carnivores. For one, there has to be more energy, because your energy flow has to reach the top of the pyramid through your primary, secondary, etc. consumers. There has to be more at the bottom because the organisms at the upper levels have to have a food source. How would the jungle look if there were 100 tigers and only 1 plant?
A severe drought in a grassland will reduce the number of consumers in the entire energy pyramid Why?

How Compare the pyramid of energy with the pyramid of number?
An energy pyramid has the producers at the bottom and the highest order consumers at the top. The bottom of the pyramid is larger than the top of the pyramid because only about 10% of the energy in one level gets to the next level. Refer to the related links for an illustration.
