organisms can be classified in three different ways: competition, predation, and symbiosis. Competition occurs when two organisms are using the same resource. Predation is the relationship where one organism consumes another. Symbiosis is a close interaction between two unlike species where at least one species benefits. These interactions are a crucial part of a functioning ecosystem. Symbiotic Relationships Many organisms rely on symbiotic relationships for survival. Symbiosis is a close interaction between two unlike species where at least one species benefits. The other organism will either be harmed, unaffected, or receive a benefit. When describing these relationships, scientists use +, 0 and - as
