What level of biological organization are Grass deer rabbits fox and bear?

Grass, deer, rabbits, foxes, and bears represent different levels of biological organization. Grass is a plant and is part of the ecosystem as a primary producer. Deer and rabbits are herbivores (primary consumers), while foxes are carnivores (secondary consumers) that prey on these herbivores. Bears, as omnivores, occupy a higher trophic level, interacting with both plant and animal species within their ecosystem. Together, they illustrate various roles within the ecological hierarchy, from individual organisms to populations and communities.
