Trophic interactions refer to the relationships between organisms in an ecosystem based on their feeding habits. These interactions are often depicted in food chains and food webs, where energy and nutrients flow from one organism to another. At the base are primary producers, like plants, which convert sunlight into energy. They are consumed by primary consumers, such as herbivores, which in turn may be eaten by secondary consumers, like carnivores. These interactions are crucial for maintaining ecological balance. They help regulate population sizes and ensure the transfer of energy through different levels of the food web. Decomposers, such as fungi and bacteria, play a vital role by breaking down dead organic matter, returning nutrients to the soil and supporting primary producers.
