Relationships in an Ecosystem

SYMBIOSIS A relationship where 2 species live closely together.

SYMBIOSIS 3 TYPES: parasitism commensalism mutualism

PARASITISM relationship where one organism feeds on the tissues or body fluids of another. Parasitism harms one organism and benefits the other. SYMBIOSIS

HOST The organism on which a parasite feeds. SYMBIOSIS: PARASITSM

A parasite may even kill its host. Most do not. SYMBIOSIS: PARASITISM: HOST

COMMENSALISM relationship where one organism benefits and the other is neither benefited nor harmed SYMBIOSIS

MUTUALISM relationship where both species benefit SYMBIOSIS
