Answer: A food chain or food web provide information on the eating patterns of organisms, how energy is transfered from one organisms to another and the flow if energy in the ecosystem.
Explanation:
Food chain is the link of network that that starts from producer to the consumer and finally ends at the predator species and decomposer species in the ecosystem. It describe the feeding relationships among organisms.
Food web contains interconnection of several food chains in the ecosystem. It shows several feeding relationships in food chains .
Both food chain and food web provide information of how organisms are interconnected, their eating patterns, how energy is transferred from one organisms to another and flow of energy in the ecosystem.
