Energy pyramids represent energy flow through trophic levels. For instance, the pyramid below shows gross productivity for each trophic level in the Silver Springs ecosystem.
Trophic levels and energy loss (article) | Khan Academy
This diagram shows three ecological pyramids: energy, biomass, and numbers. The pyramids show the amount of energy, amount of biomass, or the number of organisms in an ecosystem across trophic …
Flow of energy and cycling of matter in ecosystems
A consequence of the inefficient energy transfer between trophic levels is that there tends to be fewer organisms at higher trophic levels in an ecosystem. The number of organisms at different trophic …
Food chains & food webs (article) | Ecology | Khan Academy
Energy pyramids - The energy decreases from the lowest trophic level to the highest. Pyramids of numbers - Each level in a pyramid of numbers represents the number of organisms consumed by the …

Ecological Pyramids 1 (video) | Energy flow | Khan Academy
If we were to analyse relationships between trophic levels in an ecosystem and create a graphical representation, what shape would it be? Would it be upright? Or inverted? Watch the series of videos …

Energy flow through ecosystems Explore how energy moves through ecosystems and shapes biological interactions. Understand differences between endotherms and ectotherms in energy use. Examine …
Impact of changes to trophic pyramids (video) | Khan Academy
The trophic pyramid illustrates energy transfer within ecosystems, highlighting primary producers, consumers, and decomposers. Energy from the sun is stored as biomass, with only 10% transferred …
