0 - NEUTRAL INTERACTION

COMPETITION - IT IS A TYPE OF RELATIONSHIP WHEN TWO SPECIES COMPETE FOR THE SAME RESOURCE AND BOTH THE SPECIES LOSE IN AN INTERACTION THAT IS COMPETITIVE. EXAMPLE IS - competition amongst cheetahs and lions for food resources.

HERBIVORY - IT IS A TYPE OF RELATIONSHIP IN WHICH ONE SPECIES IS BENEFITTED WHILE THE OTHER IS HARMED. EXAMPLE IS - CATERPILLARS FEEDING ON PLANTS LEAVES.

PREDATISM - IT IS A TYPE OF RELATIONSHIP IN WHICH ONE SPECIES IS BENEFITTED WHILE THE OTHER IS HARMED. EXAMPLE IS - CARNIVOROUS INTERACTIONS SUCH AS WOLVES FEEDING ON MOOSE.

MUTUALISM - IT IS A TYPE OF RELATIONSHIP IN WHICH BOTH THE SPECIES ARE  BENEFITTED EXAMPLE IS - RELATIONSHIP BETWEEN PLANT POLLINATORS AND FLOWERING PLANTS. THE POLLINATORS RECEIVE NECTAR FROM PLANTS AND INTURN TRANSFER POLLEN FOR POLLINATION.

COMMENASLIM - IT IS A TYPE OF RELATIONSHIP IN WHICH ONE SPECIES IS BENEFITTED WHILE THE OTHER does not affect. EXAMPLE IS - BIRDS LIVING IN THE HOLLOWS OF TREES.

PARASITISM - IT IS A TYPE OF RELATIONSHIP IN WHICH ONE SPECIES IS BENEFITTED WHILE THE OTHER IS HARMED. EXAMPLE IS - TICKS LIVING ON DOGS.
