13. ECOLOGICAL PYRAMID
This shows how energy is
transferred and changed
when going up the pyramid.
14. THREE TYPES OF ECOLOGICAL
PYRAMID
A. Pyramid of Energy – shows the
amount of energy in calories (Kcal / cal)
B. Pyramid of Biomass – shows the
biomass of all organisms and individuals
C. Pyramid of Numbers – shows the
number of individuals feeding at each
tropic level
