Question

why are ecological pyramids drawn with a wide base and narrow top? it makes them easy to recognize as triangles. they represent predator - prey interactions and population changes over time. they show how biomass, population size, and energy decrease as you move up trophic levels. they allows them to always show exactly 10% energy transfer.

Explanation:

Ecological pyramids are shaped with a wide base and narrow top to visually represent the decrease in biomass, population size, and energy as one moves up the trophic levels. This graphical representation helps in understanding the flow of energy and the relationships between different organisms in an ecosystem.

Answer:

They show how biomass, population size, and energy decrease as you move up trophic levels.
