AN ECOSYSTEM IS A PLACE WHERE LIVING THINGS ARE BORN. TO KEEP THE ENVIRONMENT HEALTHY AND CLEAN YOU SHOULDN'T LITTER OR MAKE THE ENVIRONMENT DIRTY AND POLLUTED BECAUSE THE ANIMALS AND PLANTS WILL START TO DIE. MAKE SURE YOU LEAVE THE PLANTS AND ANIMALS ALONE AND DON'T KILL THEM, AND THEN WE HAVE A HEALTHY ECOSYSTEM.
