This document defines ecological relationships and describes the major types of relationships between organisms within an ecosystem. It explains that ecological relationships ensure the survival of organisms as they depend on each other for food and resources. The major relationships discussed are competition, predation, herbivory, mutualism, commensalism, and parasitism. The document emphasizes that ecological relationships are important for maintaining a stable environment where species can thrive.

IMPORTANCE OF
ECOLOGICAL
