Dear Student,
Food chain and food web represent how living organisms feed to get the energy that sustains their growth, reproduction, and movement in their respective ecological systems.
Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem. Food webs are also an important tools in understanding that plants are the foundation of all ecosystems and food chains, sustaining life by providing nourishment and oxygen needed for survival and reproduction.
