What is the difference between a food chain and a food web?
Answer:
A food chain is a linear sequence of organisms where nutrients and energy are transferred from one organism to another. It represents a single pathway of energy flow in an ecosystem. For example, plants are eaten by herbivores, which are then eaten by carnivores. It is a simplistic representation.
On the other hand, a food web is a more complex network of interconnected food chains that shows multiple pathways through which energy and nutrients can flow within an ecosystem. In a food web, various organisms are linked together, and a single organism can be part of multiple food chains. This interconnectedness better reflects the actual feeding relationships in nature.
While a food chain follows a single path, a food web is a network of interconnected food chains. Therefore, the main difference lies in the complexity of the representation and the number of potential interconnections between different organisms in an ecosystem.
