Do characteristics occupy the first level of the food chain?

Characteristics themselves do not occupy any level of the food chain; rather, they describe the traits and behaviors of organisms within it. The first level of the food chain typically consists of primary producers, such as plants and phytoplankton, which convert sunlight into energy through photosynthesis. These producers are then consumed by primary consumers, such as herbivores. Therefore, while characteristics are important for understanding how organisms function within the food chain, they do not occupy a specific level.
