"먹이망" (meogi-mang) refers to a food web, which is a complex network of feeding relationships among various organisms in an ecosystem. It illustrates how energy and nutrients flow through different levels of the ecosystem, from producers like 식물 (plants) to various levels of consumers, including 초식동물 (herbivores) and 육식동물 (carnivores). In a food web, each organism plays a specific role, contributing to the balance of the ecosystem. For example, when 초식동물 eat 식물, they obtain energy, while 육식동물 rely on 초식동물 for their energy needs. This interconnectedness highlights the importance of biodiversity in maintaining healthy ecosystems.
