The energy flow pyramid demonstrates that as you move up the food chain higher trophic levels the energy available to organisms?

Energy is transferred from the sun to the primary producers, primary consumers, secondary and tertiary consumers. Although, not all energy is passed along through the trophic levels. Energy may be dumped off in any stage of the cycle, either to start back up in a new cycle, or to be lost from the ecological cycle forever. Energy is lost through:
# Cell respiration # Feces and other waste # Unconsumed organic material (teeth, nails, fur, etc.) # Release of heat into the atmosphere Due to the loss of energy throughout the various natural processes, only about 5-20% of energy is transferred to one trophic level to the next (depending on the ecosystem), meaning 80-95% of it is lost. If only 10% of energy was transferred, then 1% of the energy the primary producers contained was transferred to the secondary consumers. This is the reason almost all food chains (few exceptions) consist of a population of low-level organisms that is larger than the population its consumers.

What does a number pyramid tell you about an ecosystem?
Shows the relative number of individual organisms at each trophic level.
Which trophic level contains the most available food energy?
On an ecological pyramid or in a food chain, typically, the highest trophic levels have the least amount of energy from the sun available for the next highest level. In a typical food chain, this would be the tertiary consumer level.
What are the similarities and differences between the aquatic trophic pyramid and the terrestrial trophic pyramid?
is a wave
Do the biomass of organisms in a typical ecological pyramid increases at each level?
The biomass of each organism decreases with each level. With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.
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.
What would biomass tell us that a pyramid of numbers wouldn't?
A pyramid of numbers will only tell you the amount of organisms at each trophic level. A Biomass pyramid ignores the amount of organisms in favour of their biomass (dry weight) which in turn represents the amount of energy available at each trophic level.

What happens to the energy that is not passed through the trophic levels of an energy pyramid?
It used by the organisms at each trophic level to keep themselves alive.
What percent of the energy available within on trophic level is transferred to organisms at the next trophic level when they are eaten?
1%
What trophic levels is at the base of each energy pyramid?
Usually Producers are at the bottom of the energy pyramid such as Grass, Fungi, dead leaves, ect.

Why is ecological pyramid shaped like a pyramid?
A graphical model that is shaped like a pyramid to show how the energy flows through a food chain, how the amount of energy is decreasing and becoming less available for organisms as it enters each trophic level, and how much of the energy in the ecosystem is lost to the atmosphere as heat.
