Verified step by step guidance1
Understand that an ecological pyramid is a graphical representation used in ecology to show the relationship between different organisms in an ecosystem.
Recognize that ecological pyramids can represent three different types of data: biomass, numbers, or energy at each trophic level.
Identify that the pyramid shape is due to the decrease in available energy, biomass, or number of organisms as you move up the trophic levels from producers to apex predators.
Differentiate between the types of ecological pyramids: Pyramid of Numbers (shows the number of organisms), Pyramid of Biomass (shows the total mass of organisms), and Pyramid of Energy (shows the flow of energy).
Clarify that ecological pyramids do not depict genetic variation within a population or illustrate the water cycle, as these are unrelated concepts.
