Why all the animalia Kingdom don't have chlorophyll

Answer»

Chlorophyll is needed for photosynthasis....
ORGANISMS evolved them for PREPARING food themselves....

organisms who could take food from other organisms had no need to prepare their food ....so they were not evolved for synthasizing their food and they carried on TAKING food from others....

THATS why all the anamiliabkingdom do not have chlorophyll because there is no need of chlorophyll in hetrotropic organisms..

i HOPE it will help you
