Trophic level, step in a nutritive series, or food chain, of an ecosystem.The organisms of a chain are classified into these levels on the basis of their feeding behaviour.The first and lowest level contains the producers, green plants.The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. bacteria) and between members of different trophic levels (guilds) within a food web (e.g., phage–bacteria, protozoa– bacteria, protozoa–phage) may … 9710). Explain to students that a food pyramid shows how organisms are connected to one another in a food chain, as well as how much energy is transferred from one trophic level to the next. Relationships between species (e.g., bacteria–bacteria) and between members of different trophic levels (guilds) within a food web (e.g., phage–bacteria, protozoa–bacteria, protozoa–phage) may be mutualistic or antagonistic, both fostering community development through co-evolutionary processes.
