					           ENERGY PYRAMID, BIOMASS PYRAMID, AND PYRAMID OF NUMBERS

Using the pyramids below, draw an energy pyramid, biomass pyramid, and pyramid of numbers for a four step food chain
(you may use any 4 organisms you would like, but use different organisms for each type of pyramid). Provide a brief
description of what the pyramid is depicting. Then answer the question(s) relating to the type of pyramid you have drawn.
Be sure to use lots of color!!!

                                                         TYPE: ENERGY PYRAMID

                                                         DESCRIPTION:




                                                         HOW MUCH OF THE ENERGY THAT IS AVAILABLE AT ONE
                                                         TROPHIC LEVEL OF THE PYRAMID IS TRANSFERRED TO
                                                         ORGANISMS AT THE NEXT TROPHIC LEVEL?




                                                         TYPE: BIOMASS PYRAMID

                                                         DESCRIPTION:




                                                         IF THERE ARE 1500 GRAMS OF BIOMASS AT THE BOTTEM OF
                                                         YOUR BIOMASS PYRAMID, HOW MANY GRAMS OF BIOMASS
                                                         WOULD BE REPRESENTED BY THE TOP LEVEL OF THE
                                                         PYRAMID?




                                                         TYPE: PYRAMID OF NUMBERS

                                                         DESCRIPTION:




                                                         EXPLAIN WHY ARE THERE MORE ANIMALS DEPICTED ON
                                                         THE BOTTEM OF YOUR PYRAMID OF NUMBERS THAN THERE
                                                         ARE AT THE TOP LEVEL?
